mmc: sdhci-brcmstb: Initialize base_clk to NULL in sdhci_brcmstb_probe()
Clang warns a few times along the lines of:
drivers/mmc/host/sdhci-brcmstb.c:302:6: warning: variable 'base_clk' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]
if (res)
^~~
drivers/mmc/host/sdhci-brcmstb.c:376:24: note: uninitialized use occurs here
clk_disable_unprepare(base_clk);
^~~~~~~~
base_clk is used in the error path before it is initialized. Initialize
it to NULL, as clk_disable_unprepare() calls clk_disable() and
clk_unprepare(), which both handle NULL pointers gracefully.
