As code already used CBMEM hooks to switch from CAR to CBMEM
it was never necessary to have the structure declared inside
_car_relocatable_data.
Switch to use car_[get|set]_ptr is mostly for consistency, but
should also enable use of usbdebug with FSP1.0 romstage.

The documentation for StackBase and StackSize in FSPM_ARCH_UPD is
confusing. Previously the region was shared for heap and stack,
starting with FSP2.1 only for heap (or 'temporary RAM') for HOBs.
Moving the allocation outside DCACHE_BSP_STACK_SIZE allows use of
stack guards and reduces amount of reserved CAR for bootblock and
verstage, as the new allocation in .bss is only taken in romstage.

Summary:
Added a framework to search VPD in romstage before memory is
avilable. vpd_cbmem.c and vpd_premem.c are added for
code specific for premem environment and for environment that
cbmem can be used.
Since global variable is forbidden in romstage. A CAR_GLOBAL
variable is defined in vpd.c. This variable holds VPD binary
blobs' base address and size from memory mapped flash.
The overall flow is:
* The CAR variable g_vpd_blob is initialized if it was not,
either at romstage (before FSP-M execution in case of FSP UPD
customization), or at ramstage.
* At ramstage, during CBMEM_INIT, the VPD binary blob contents
are copied into CBMEM.
* At vpd_find() which may be called at romstage or at ramstage,
it sets storage for a local struct vpd_blob variable.
* The variable gets contents duplicated from g_vpd_blob, if
vpd_find() is called at romstage.
* The variable gets contents obtained from CBMEM, if vpd_find()
is called at ramstage.
Added a call vpd_get_bool(). Given a key/value pair in VPD
binary blob, and name of a bool type variable, set the variable
value if there is a match.
Several checks are in place:
* The key/value length needs to be correct.
* The key name needs to match.
* THe value is either '1' or '0'.
Test Plan:
* Build an OCP MonoLake coreboot image, flash and run.

Variable length arrays were a feature added in C99 that allows the
length of an array to be determined at runtime. Eg.
int sum(size_t n) {
int arr[n];
...
}
This adds a small amount of runtime overhead, but is also very
dangerous, since it allows use of an unlimited amount of stack memory,
potentially leading to stack overflow. This is only worsened in
coreboot, which often has very little stack space to begin with. Citing
concerns like this, all instances of VLA's were recently removed from the
Linux kernel. In the immortal words of Linus Torvalds [0],
AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and
much _slower_ code (and more fragile code), than just using a fixed
key size would have done. [...] Anyway, some of these are definitely
easy to just fix, and using VLA's is actively bad not just for
security worries, but simply because VLA's are a really horribly bad
idea in general in the kernel.
This patch follows suit and zaps all VLA's in coreboot. Some of the
existing VLA's are accidental ones, and all but one can be replaced with
small fixed-size buffers. The single tricky exception is in the SPI
controller interface, which will require a rewrite of old drivers
to remove [1].
