Subject: [PATCH][media] atomisp: make repool_pgnr and punit_ddr_dvfs_enable static

From: Colin Ian King <colin.king@...onical.com>

integer repool_pgnr and function punit_ddr_dvfs_enable can be made
static as they do not need to be in global scope.

Cleans up sparse warnings:
 "symbol 'repool_pgnr' was not declared. Should it be static?"
 "symbol 'punit_ddr_dvfs_enable' was not declared. Should it be static?"
