Exposing set/way cache maintenance to a virtual machine is unsafe, not
least because the instructions are not permission-checked but also
because they are not broadcast between CPUs. Consequently, KVM traps and
emulates such maintenance in the host kernel using by-VA operations and
looping over the stage-2 page-tables. However, when running under
protected KVM, these instructions are not able to be emulated and will
instead result in an exception being delivered to the guest.
Introduce CONFIG_CMO_BY_VA_ONLY so that virtual platforms can select
this option and perform by-VA cache maintenance instead of using the
set/way instructions.

- Partial merge of a series of mine to select some framework options
that shouldn't be prompted for (and remove some unused code related to
that), and a partial merge of a series from Simon to remove some dead

At present we compile commands into U-Boot SPL even though they cannot
be used. This wastes space. Adjust the condition to avoid this.

The conditions in this code do not align when doing an SPL build with
split config. Use __maybe_unused to avoid needing to be so explicit.
Of course a better solution would be to refactor all of this to avoid
using #ifdef.

This causes a build failure on mx6cuboxi with split config, since CMD_SATA
shows up as enabled in SPl (because there is no SPL_CMD_SATA).

There are 4 USB controllers on MT8195, the controllers (IP1~IP3,
exclude IP0) have a wrong default SOF/ITP interval which is
calculated from the frame counter clock 24Mhz by default, but
in fact, the frame counter clock is 48Mhz, so we shall set the
accurate interval according to 48Mhz for those controllers.
Note:
The first controller no need set it, but if set it, shall change
tphy's pll at the same time.

The T-PHY controller is designed to use use PLL integer mode, but
in fact use fractional mode for some ones on mt8195 by mistake,
this causes signal degradation (e.g. eye diagram test fail), fix
it by switching PLL to 26Mhz from default 48Mhz to improve signal
quality.
