Now all linker symbols are declared as type char[]. Though we can
reference the address via both the array name 'var' and its address
'&var'. It's better to unify them to avoid confusing developers.
This patch converts all '&var' linker symbol refrences to the most

It is not a parse error to have a default value of "0" for a "hex" type
entry, instead of "0x0". However, "0" and "0x0" are not treated the
same even by the tools themselves. Correct this by changing the default
value from "0" to "0x0" for all hex type questions that had the
incorrect default. Fix one instance (in two configs) of a default of "0"
being used on a hex question to be "0x0". Remove the cases where a
defconfig had set a value of "0x0" to be used as the default had been
"0".

Both the Linux kernel and libbsd agree that strlcpy() should always
return strlen(src) and not include the NUL termination. The incorrect
U-Boot implementation makes it impossible to check the return value for
truncation, and breaks code written with the usual implementation in
mind (for example, fdtdec_add_reserved_memory() was subtly broken).
I reviewed all callers of strlcpy() and strlcat() and fixed them
according to my understanding of the intended function.
This reverts commit d3358ecc54 and adds
related fixes.

Move the ethernet gadget driver registration and removal from ethernet
bind and unbind callbacks into driver DM probe and remove callbacks.
This way, when the driver is bound, which is triggered deliberately
using 'bind' command, the USB ethernet gadget driver is instantiated
and bound to the matching UDC. In reverse, when the driver is unbound,
which is again triggered deliberately using 'unbind' command, the USB
ethernet gadget driver instance is removed.
Effectively, this now behaves like running either 'ums' or 'dfu' or
any other commands utilizing USB gadget functionality.
This also drops use of usb_gadget_release() and moves the use of
usb_gadget_initialize() into usb_ether_init() used only by legacy
platforms that do not use 'bind' command properly yet. Those have
no place in drivers.

There exists a situation of the mediatek pinctrl driver that may return
wrong pin function value for the pinmux driver:
- All pin function arrays are defined without const
- Some pin function arrays contain all-zero value, e.g.:
static int mt7622_spi_funcs[] = { 0, 0, 0, 0, 0, 0, };
- These arrays will be put into .bss section during compilation
- .bss section has no "a" attribute and does not exist in the final binary
file after objcopy.
- FDT binary blob is appended to the u-boot binary, which occupies the
.bss section.
- During board_f stage, .bss has not been initialized, and contains the
data of FDT, which is not full-zero data.
- pinctrl driver is initialized in board_f stage, and it will get wrong
data if another driver is going to set default pinctrl.
Since pinmux information and soc data are only meant to be read-only, thus
should be declared as const. This will force all pinctrl data being put
into .rodata section. Since .rodata has "a" attribute, even the all-zero
data will be allocated and filled with correct value in to u-boot binary.
