Currently there is one DRAM parameter struct for the Allwinner H616 DRAM
"driver". It contains many fields that are compile time constants
(set by Kconfig variables), though there are also some fields that are
probed and changed over the runtime of the DRAM initialisation.
Because of this mixture, the compiler cannot properly optimise the code
for size, as it does not consider constant propagation in its full
potential.
Help the compiler out by splitting that structure into two: one that only
contains values known at compile time, and another one where the values
will actually change. The former can then be declared "const", which will
let the compiler fold its values directly into the code using it.
We also add "const" tags for some new "struct dram_config" pointers, to
further increase code optimisation.
To help the compiler optimise the code further, the definition of the
now "const struct dram_para" has to happen at a file-global level, so
move that part out of sunxi_dram_init().
That results in quite some code savings (almost 2KB), and helps to keep
the code small with the LPDDR3 support added later.

There are quite some functions in the Allwinner H616 DRAM "driver", some
of them actually change the parameters in the structure passed to them,
but many are actually not.
To increase the optimisation potential for the code, mark those functions
that just read members of the passed dram_para struct as "const".
This in itself does not decrease the code size, but lays the groundwork
for future changes doing so.

The usage of the C keyword "inline" seems to be a common
misunderstanding: it's a *hint* only, and modern compilers will inline
(or not) functions based on their own judgement and provided compiler
options.
So while marking functions as "inline" does not do much, missing the
"static" keyword will force to compiler to spell out a version of the
function for potential external callers, which actually increases the
code size (though hopefully the linker will drop the function).
Change the "inline" attribute for the mbus_configure_port() functions in
some Allwinner DRAM drivers to "static", so that the explicit version
can actually be dropped from the object file, reducing the code size.
"static inline" has a use case in header files, where it avoids a warning
if a .c file including this header does not use the particular function.
In a .c file itself "static inline" is not useful otherwise, so just use
static here as well.

correctly: The CLK_BUS_PHY2 and RST_USB_PHY2 clock and reset need to be
enabled, and the SIDDQ bit in the PMU PHY control register needs to be
cleared. For this register to be accessible, CLK_BUS_ECHI2 needs to be
ungated. Don't ask ....
Follow the respective Linux patch (b45c6d80325b) and add a quirk bit,

At the moment we use "select" in each Allwinner SoC's Kconfig section to
include the USB PHY driver in the build. This means it cannot be disabled
via Kconfig, although USB is not really a strictly required core
functionality, and a particular board might not even include USB ports.
Rework the Kconfig part by removing the "select" lines for each SoC's
section, and instead letting it default to "y" in the PHY driver section
itself. We use "depends on !" to exclude the few SoCs we don't support
(yet). The Allwinner V3s does not enable USB (PHY) support at the moment,
even though it should work: let the PHY default to "n" to keep the
current behaviour.
Also the MUSB USB driver directly calls some functions from the PHY
driver, so let the former depend on the PHY driver.

In its of_xlate() function, the Allwinner USB PHY driver compares the
args_count variable against the number of implemented USB PHYs, although
this is the *number of arguments* to the DT phandle property. Per the DT
binding for this PHY device, this number is always one, so this check
will always fail if the particular SoC implements exactly one USB PHY.
So far this affected only the V3s (which has USB support disabled), but
the F1C100s also sports one PHY only.
Fix that check to compare args_count against exactly 1, and the args[0]
content (requested PHY number) against the number of implemented PHYs.
This fixes USB operation on the Allwinner V3s and allows to enable USB
