exynos5420: get rid of old exynos5420_config_l2_cache()
We set up L2 cache early in romstage now so the old
function is now redundant.

exynos: stack size: Increase the stack size to 16KB.
The lzma decoding function in the RAM stage allocates nearly 16KB on the stack
which is shared between the bootblock, rom stage, and ram stage. The stack had
been much too small and needed to be expanded.

Z-state pins were not reading reliably with a 5us delay, so increase
it to 15us.

exynos5420: Correct the 600MHz PMS value
In UM ver0.02, 600MHz clock PMS values differs from what is programed
currently. Though this also results in 600MHz clock, but it is better to
match what UM says. This patch chnage this as per UM

(Note: we already used the correct 600MHz value for KPLL)
