mips: add a mtmips-specific field to architecture-specific global data

SoCs of mtmips can use different CPU frequencies depending on the HW/SW
configurations. For example mt7628 uses 580MHz clock if the input xtal
frequency is 40MHz, and 575MHz clock if the xtal is 25MHz. Upon cold boot
the CPU uses the xtal frequency directly.

So hardcoding the timer frequency (half of the CPU frequency) in
CONFIG_SYS_MIPS_TIMER_FREQ is not a good idea for this case.

mips: start.S: avoid overwriting outside gd when clearing global data in stack

When setting up initial stack, global data will also be put in the stack,
and being cleared.

The assembler instructions for clearing gd is as follows:

move t0, k0
1:
PTR_S zero, 0(t0)
blt t0, t1, 1b
 PTR_ADDIU t0, PTRSIZE

t0 is the start address of gd, t1 is the end address of gd (t0 + GD_SIZE).

[PTR_ADDIU t0, PTRSIZE] is in the delay slot of [blt t0, t1, 1b], so it
will be executed before the branch operation.

However the comparison for the BLT instruction is done before executing the
delay slot. This means when the last word just before k1 is cleared, the
loop will continue to run once. This will clear an extra word at k1, which
is outside the global data.

Global data is placed at the top of the stack. If the initial stack is a
SRAM or locked cache, the area outside them may be inaccessible. A write
operation performed in this area may cause an exception.

To solve this, [PTR_ADDIU t0, PTRSIZE] should be placed before the BLT
instruction.

The current definition of the env_save_ptr does not take SPL_SAVEENV

need to guard the definitions of their _save methods with ifdefs to
avoid "defined but unused" warnings in case CMD_SAVEENV=n.

The ifdeffery can be avoided by using a "something ? x : NULL"
construction instead and still have the compiler elide the _save
method when it is not referenced. Unfortunately we can't just switch
the existing env_save_ptr macro, since that would give a lot of build
errors unless all the ifdeffery is removed at the same time.
Conversely, removing that ifdeffery first would merely lead to the
"defined but unused" warnings temporarily, but for some storage
drivers it requires a bit more work than just removing their private
CMD_SAVEENV logic.

So introduce an alternative to env_save_ptr, which for lack of a
better name is simply uppercased, allowing one to update storage
drivers piecemeal to both reduce their ifdeffery and honour
