clk: berlin: bg2q: remove non-exist "smemc" gate clock

commit b71e8ecd upstream.

The "smemc" clock is removed on BG2Q SoCs. In fact, bit19 of clkenable
register is for nfc. Current code use bit19 for non-exist "smemc"
incorrectly, this prevents eMMC from working due to the sdhci's
"core" clk is still gated.
