Add support and enalbe cache-as-ram paging for glk to work around
a cache-as-ram corruption issue. glk executes verstage, romstage,
and FSP-M directly out of cache-as-ram (just like apl). However,
the front end on glk is very agressive about pulling cache lines
into L1I for potential execution. When the snoops hit in the L1D
and the cache lines are dirty the processor writes the line back.
However, there is no backing store for the dirty lines to go. As
such when the line is pulled back in the value is all 0xff's,
corrupting cache-as-ram.
To fix the issue one needs to enable paging with NX (no execute)
permissions which prevents the above actions from happening because
the TLB will indicate that shouldn't be fetched into the instruction
cache since data will be marked no execute.
The generated page tables are added to cbfs and only added to the
COREBOOT cbfs as they are only consumed in the early cache-as-ram
stages.
The page tables generated with:
$ go run util/x86/x86_page_tables.go \
--iomap_file=src/soc/intel/apollolake/glk_page_map.txt \
--metadata_base_address=0xfef00000 \

When smi.h is included to southbridge.h (to use SCI/SMI definitions within
southbridge.h definitions), this causes a collision of the definition of NONE
(ioapic.h also has a NONE definition). As NONE is an enumeration of interrupt
types (SCI/SMI), add INTERRUPT_ at the start of each definition.
This is preparation to have GPIO table/code also declare/program SCI/SMI.

Add Kconfig IDT_IN_EVERY_STAGE to optionally specify having
the interrupt handling code available to all stages. In order
to do this the idt setup is moved to a C module. The vecX
entries are made global so that a table of references to all
the interrupt vector entry points can be used to dynamically
initialize the idt. The ramification for ramstage is that
exceptions are initialized later (lib/hardwaremain.c). Not
all stages initialize exceptions when this Kconfig variable
is selected, but bootblock for the C, stages using
assembly_entry.S, and of course ramstage do. Anything left
out just needs a call to exception_init() at the right
location.
