tpm: Do not remap from ACPI resources again for Pluton TPM
For Pluton TPM devices, it was assumed that there was no ACPI memory
regions. This is not true for ASUS ROG Ally. ACPI advertises
0xfd500000-0xfd5fffff.
Since remapping is already done in `crb_map_pluton`, remapping again
in `crb_map_io` causes EBUSY error:
[ 3.510453] tpm_crb MSFT0101:00: can't request region for resource [mem 0xfd500000-0xfd5fffff]
[ 3.510463] tpm_crb: probe of MSFT0101:00 failed with error -16
Cc: stable@vger.kernel.org # v6.3+
Fixes: 4d2732882703 ("tpm_crb: Add support for CRB devices based on Pluton")
