mmc: dw_mmc: hi3798cv200: make array degrees static const, makes object smaller

Don't populate the array degrees on the stack but instead make it
static const. Makes the object code smaller by 46 bytes.

Before:
text data bss dec hex filename
5356 1560 0 6916 1b04 dw_mmc-hi3798cv200.o

After:
text data bss dec hex filename
5214 1656 0 6870 1ad6 dw_mmc-hi3798cv200.o

(gcc version 9.2.1, amd64)
