Subject: [PATCH v2 1/3] memory: Exynos5422: minor fixes in DMC

Small fixes for issues captured by static analyzes:
used kfree() insead of devm_kfree() and missing 'static' in the private
function.
Checks which show the issues:
- drivers/memory/samsung/exynos5422-dmc.c:272 exynos5_init_freq_table()
warn: passing devm_ allocated variable to kfree. 'dmc->opp'
- drivers/memory/samsung/exynos5422-dmc.c:736:1: warning: symbol
'exynos5_dmc_align_init_freq' was not declared.
