[PATCH v1 1/3] mmc: msm_sdhci: fix max-frequency read into wrong-sized variable

msm_sdc_clk_init() reads the "max-frequency" DT property with
dev_read_u32(dev, "max-frequency", (uint *)(&clk_rate)), writing
only 4 bytes into clk_rate, an 8-byte ulong. The upper 4 bytes are
left uninitialized whenever the property is present. Read into a
u32 local instead, then assign it to clk_rate.
