[PATCH v2 0/2] tegra_mmc: get tap and trim from dts

Default-tap and default-trim values are used for eMMC setup
mostly on T114+ devices. As for now, those values are hardcoded
for T210 and ignored for all other Tegra generations. Fix this
by passing tap and trim values from dts.

Changes from v1
- move t210 device tree fix into this series
- switch dev_read_u32_default > dev_read_u32
- if reading of device tree tap/trim values returns error
  store error in entries of driver structure
- apply tap and trim only if they pass error check
