Shawn Lin 5b43df8b4c mmc: dw_mmc: Avoid accessing registers in runtime suspended state 
cat /sys/kernel/debug/mmc0/regs will hang up the system since
it's in runtime suspended state, so the genpd and biu_clk is
off. This patch fixes this problem by calling pm_runtime_get_sync
to wake it up before reading the registers.

Fixes: e9ed8835e990 ("mmc: dw_mmc: add runtime PM callback")
