src/cpu: drop CPU_X86_CACHE_HELPER and x86_enable_cache wrapper function

Selecting CPU_X86_CACHE_HELPER only added the x86_enable_cache wrapper
function around enable_cache which additionally wrote a POST code to
port 0x80 and printed a message to the console. This function was only
called during multi-processor initialization in ramstage via the init
function pointer in the CPU's device operations struct and was run on
all cores, so the message on the console was printed once per CPU core.

This patch replaces all x86_enable_cache calls by calls to enable_cache
and removes the wrapper function and the Kconfig symbol
CPU_X86_CACHE_HELPER which was used to only add this when the
corresponding CPUs used the x86_enable_cache wrapper function.
