[PATCH v3 15/21] mmc: renesas-sdhi: Refactor probe function

[Paul Barker]

Move the assignment of priv->quirks earlier in the function. This allows
us to drop the quirks local variable and makes it easier to maintain
clean error handling when we add RZ/G2L support in the next patch.

v2->v3:
  * Added Marek's Reviewed-by.
v1->v2:
  * New patch to support breaking out RZ/G2L-specific initialization
    into its own function.
