MIPS: Move processing of coherency kernel parameters earlier

MIPS: Move processing of coherency kernel parameters earlier

Commit 67a862de4ca0434009ca934d3ba56c13f4206fb0 (jump-label: initialize
jump-label subsystem much earlier) caused MIPS to break, so this was
resolved with commit c63c9e01567aedd816fc347dc5698549bbaaef64 (MIPS:
Move cache setup to setup_arch().).  Unfortunately, after this commit,
the coherency kernel parameters, cca and coherentio, are no longer
processed before their values are used.

This patch fixes this problem by marking them as early_param, which
results in them being processed before they are needed.
