soc: fsl: qe: avoid IS_ERR_VALUE in ucc_slow.c

When trying to build this for a 64-bit platform, one gets warnings
from using IS_ERR_VALUE on something which is not sizeof(long).

Instead, change the various *_offset fields to store a signed integer,
and simply check for a negative return from qe_muram_alloc(). Since
qe_muram_free() now accepts and ignores a negative argument, we only
need to make sure these fields are initialized with -1, and we can
just unconditionally call qe_muram_free() in ucc_slow_free().

Note that the error case for us_pram_offset failed to set that field
to 0 (which, as noted earlier, is anyway a bogus sentinel value).
