[IA64] fix "allnoconfig" build
Link errors:
arch/ia64/kernel/built-in.o: In function `arch_setup_dmar_msi':
(.text+0x35972): undefined reference to `dmar_msi_write'
... and more ...
because allnoconfig has CONFIG_DMAR=y due to the "select DMAR"
in arch/ia64/Kconfig under config IA64_GENERIC.
Drop that select, but add CONFIG_DMAR=y to generic_defconfig so
we keep testbuilding the DMAR code.
