eef88dfb3e MIPS: unify CPU code in arch/mips/cpu/
Unify and move code in arch/mips/cpu/mips[32|64]/ to arch/mips/cpu/.
The CPU specific config.mk files need to remain until
CONFIG_STANDALONE_LOAD_ADDR is converted to a global Kconfig symbol.

a18a477147 MIPS: use common code from lib/time.c
The common code just needs the C0_COUNT as free running counter,
without the need of writing and checking C0_COMPARE.

The function get_tbclk() is still implemented here instead of changing
all places of CONFIG_SYS_MIPS_TIMER_FREQ to CONFIG_SYS_TIMER_RATE.

The change was tested on a MIPS32 system, but as the MIPS64 code
was/is the same, this should be no problem.

c3e4901fc6 MIPS: mips32/time.c: fix checkpatch errors/warnings
Checking mips32/time.c with checkpatch.pl shows this:

  arch/mips/cpu/mips32/time.c:30: WARNING: line over 80 characters
  arch/mips/cpu/mips32/time.c:57: ERROR: return is not a function, parentheses are not required
  total: 1 errors, 1 warnings, 0 checks, 85 lines checked

Fix the code to make checkpatch.pl happy.

8ab36d2e54 MIPS: do not initialize timestamp variable before relocate_code
Because timestamp is declared as `static', we needn't initialize
it by writing it a zero. If we do it before relocate_code, we
will write into a flash address(0xffffffffbfc0xxxx).

68cebb8027 MIPS: Move timer code to arch/mips/cpu/$(CPU)/
Current timer routines (arch/mips/lib/timer.c) are implemented assuming
that MIPS32 coprocessor (CP0) resources, Counter and Compare registers
in this case, are available.  But this doesn't always work.

We need to make sure that all MIPS-based systems don't necessarily use
CP0 counter/compare registers as time keeping resources.  And some MIPS
variant processors might come with different hardware specs with genuine
MIPS32 CP0 registers.

With this change, each $(CPU)/ directory can have its own timer code.
