remoteproc: use SIZE_MAX in rproc_u64_fit_in_size_t()

Smatch reports:

drivers/remoteproc/remoteproc_elf_loader.c:221
warn: always true condition '(val <= -1)'

The helper function rproc_u64_fit_in_size_t() compares the value
against (size_t)-1, which is equivalent to SIZE_MAX but can confuse
static analysis tools and lead to the above warning.

Replace (size_t)-1 with SIZE_MAX to make the intent explicit and
avoid the Smatch warning without changing the behavior.
