This CPU core is old, no boards using the CPU are left in mainline,
it has no prospects of ever being converted to DM, drop it.

Replace those two functions with generic ones by defining the
timer macros in include/config/*.h .

The code uses all in all three TMU registers, drop the massive
register layout structures and just define the required timer
registers and use them throughout the code.

The header contains only the TMU register layout, just inline it
into the TMU timer implementation and drop the header completely.

The R-Car Gen2 feeds the TMU with CONFIG_SYS_CLK_FREQ / 2,
while the old SH parts use CONFIG_SYS_CLK_FREQ directly.
Just put this into the TMU implementation and drop the
CONFIG_SH_TMU_CLK_FREQ config option.

This function just returns CONFIG_SH_TMU_CLK_FREQ, use the constant
directly instead.

These functions are always called for timer = 0, so drop the
timer check. Since these functions are called from one place
only and they are reduced to one line of code, just inline
them.

The tmu_bit value evaluates to (ffs(4) >> 1) - 1 = (3 >> 1) - 1 = 0.
Just drop the tmu_bit completely as well as CONFIG_SYS_TMU_CLK_DIV.

This constant is always 4 , for all boards that exist. Define it
once in arch/sh/lib/time.c and remove it from the configs.
