Nathan Chancellor fecd236ef6 ASoC: mchp-spdifrx: Fix uninitialized use of mr in mchp_spdifrx_hw_params()
[ Upstream commit 218674a459 ]

Clang warns:

  ../sound/soc/atmel/mchp-spdifrx.c:455:3: error: variable 'mr' is uninitialized when used here [-Werror,-Wuninitialized]
                  mr |= SPDIFRX_MR_ENDIAN_BIG;
                  ^~
  ../sound/soc/atmel/mchp-spdifrx.c:432:8: note: initialize the variable 'mr' to silence this warning
          u32 mr;
                ^
                 = 0
  1 error generated.

Zero initialize mr so that these bitwise OR and assignment operation
works unconditionally.
