IMA: allow/fix UML builds
UML supports HAS_IOMEM since 0bbadafdc49d (um: allow disabling NO_IOMEM). Current IMA build on UML fails on allmodconfig (with TCG_TPM=m): ld: security/integrity/ima/ima_queue.o: in function `ima_add_template_entry': ima_queue.c:(.text+0x2d9): undefined reference to `tpm_pcr_extend' ld: security/integrity/ima/ima_init.o: in function `ima_init': ima_init.c:(.init.text+0x43f): undefined reference to `tpm_default_chip' ld: security/integrity/ima/ima_crypto.o: in function `ima_calc_boot_aggregate_tfm': ima_crypto.c:(.text+0x1044): undefined reference to `tpm_pcr_read' ld: ima_crypto.c:(.text+0x10d8): undefined reference to `tpm_pcr_read' Modify the IMA Kconfig entry so that it selects TCG_TPM if HAS_IOMEM is set, regardless of the UML Kconfig setting. This updates TCG_TPM from =m to =y and fixes the linker errors.
