Subject: [PATCH] mfd: fix dependency warning for CHROME_PLATFORMS on !X86, !ARM

In commit 062476f24aa7cf714169342cc50626fd9bbb93da ("mfd: cros_ec:
Move protocol helpers out of the MFD driver") there was a select
added on CHROME_PLATFORMS, which leads to the following for ppc/mips:

warning: (MFD_CROS_EC) selects CHROME_PLATFORMS which has unmet
direct dependencies (X86 || ARM)

Presumably the above means MFD_CROS_EC is only currently useful
on x86 and ARM, so lets limit it to there.
