8991fed97d mips: Remove common.h usage
We can remove common.h from most cases of the code here, and only a few
places need an additional header instead.

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

04d21a93fa mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations
The current implementations have some issues detecting the correct
values:

dqs_find_max() will return "last passing fieldval + 1" instead of
"last passing fieldval". Also it will return "maxval + 1" in the
case that all fieldvals are tested valid (without error).

dqs_find_min() will not test the "lowest" value because of using ">"
instead of ">=".

This patch now rewrites these functions to fix those issues. Also,
this patch uses the same approach of a for loop in both functions making
it easier to read and maintain.

Since the variables are integers now, we can use min()/max(), which
handles the wrap around case for fieldval=0: return (0 - 1).

112add362b mips: mt76x8: ddr_cal: Change types from u32 to int in dqs_find_min/max
This change is made to enable comparison of integer variables, which
might be negative in the next patch. No functional change is intended
in this patch.

896449fa29 mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error()
This function returns "-1" (true) upon error. So the function name does
not match its implementation which is confusing. This patch renames the
function to dqs_test_error() which makes the code easier to read.

Also change the return type to bool and return "true" or "false".

02cd449f0b mips: mtmips: rewrite lowlevel codes of mt7628
This patch rewrites the mtmips architecture with the following changes:

1. Move MT7628 soc parts into a subfolder.
2. Lock parts of D-Cache as temporary stack.
3. Reimplement DDR initialization in C language.
4. Reimplement DDR calibration in a clear logic.
5. Add full support for auto size detection for DDR1 and DDR2.
6. Use accurate CPU clock depending on the input xtal frequency for timer
   and delay functions.

Note:

print_cpuinfo() has incompatible parts with MT7620 so it's moved into
mt7628 subfolder.
