Bhushan Shah 03864e5777 ARM: dts: qcom: msm8974-hammerhead: increase load on l20 for sdhci
The kernel would not boot on the hammerhead hardware due to the
following error:

mmc0: Timeout waiting for hardware interrupt.

This patch increases the load on l20 to 0.2 amps for the sdhci
and allows the device to boot normally.
