Subject: IMA: allow/fix UML builds

From: Randy Dunlap <rdunlap at infradead.org>

commit 644f17412f5acf01a19af9d04a921937a2bc86c6 upstream.

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.
