s390/cmma: move parsing of cmma kernel parameter to early boot code
The "cmma=" kernel command line parameter needs to be parsed early for upcoming changes. Therefore move the parsing code. Note that EX_TABLE handling of cmma_test_essa() needs to be open-coded, since the early boot code doesn't have infrastructure for handling expected exceptions.
