Revert "board_f: Use static print_cpuinfo if CONFIG_CPU is active"

This reverts commit c0434407.

It turns out commit c0434407 broke some boards which have DM CPU
driver with CONFIG_DISPLAY_CPUINFO option on. These boards just fail
to boot when print_cpuinfo() is called during boot.

Fixes are already sent to ML and in u-boot-dm/next, however since
we are getting close to the v2018.11 release, it's safer we revert
the original commit.

This commit should be reverted after v2018.11 release.
