[PATCH v3 1/2] memory: samsung: exynos5422-dmc: Fix kfree() of devm-allocated memory and missing static

[Lukasz Luba <l.luba@partner.samsung.com>]

Fix issues captured by static checkers: used kfree() and missing 'static'
in the private function.

Fixes Smatch warning:
    drivers/memory/samsung/exynos5422-dmc.c:272
        exynos5_init_freq_table() warn: passing devm_ allocated variable to kfree. 'dmc->opp'

Fixes Sparse warning:
    drivers/memory/samsung/exynos5422-dmc.c:736:1:
        warning: symbol 'exynos5_dmc_align_init_freq' was not declared.
