asmc: fix asmc_key_dump() page fault on T2 MMIO backend
asmc_key_dump() used I/O port macros (ASMC_DATAPORT_WRITE/READ,
asmc_command()) unconditionally. On T2 Macs, sc_ioport is NULL
(MMIO backend is used instead), causing a page fault when
ASMC_DEBUG triggers asmc_dumpall() during attach.
Add an MMIO guard at the top of asmc_key_dump(): delegate to
asmc_key_dump_by_index() + asmc_key_read() for MMIO devices,
consistent with the rest of the T2 code paths.
