[PATCH] rtc: snvs: select option REGMAP_MMIO

[Shawn Guo]

Select REGMAP_MMIO to fix the following build error seen with x86_64
randconfig.

  drivers/built-in.o: In function `snvs_rtc_probe':
rtc-snvs.c:(.text+0x567730): undefined reference to `devm_regmap_init_mmio_clk'

Reported-by: kbuild test robot <fengguang.wu at intel.com>

This is a fix to patch "rtc: snvs: use syscon to access register",
which I queued on IMX tree for 4.3.  So I will apply it to the same
branch.
