Padmelon board code was written for Merlin Falcon (family 15h models 60h-6fh),
but as the needed binaries are not yet merged (commit 33615), a config
HAVE_MERLINFALCON_BINARIES was added. If the binaries are not available,
the board defaults to Prairie Falcon, which use the same binaries as Stoney
Ridge. Once the binaries are merged, the config will be eliminated. Fan
control is done through F81803A SIO, and IRQ/GPIO and other board
characteristics are the same regardless of Merlin Falcon or Prairie Falcon.
Padmelon board was created to accept Prairie Falcon, Brown Falcon and Merlin
Falcon. The requested development was for Merlin Falcon. There are some small
spec changes (such as number of memory channels) between SOCs. Brown Falcon
was not investigated, Prairie Falcon is very similar to Stoney Ridge.
Started from Gardenia code, added changes created by Marc Jones and finally
revised against schematic, which added changes to GPIO settings.

* Flash the image to MonoLake, boot and observe following

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.

This format of PCH GPIOs configuration, unlike the raw DW0 and DW1 [1]
registers values from the inteltool dump, is more understandable and
makes the code much cleaner. The pad configuration in this patch was
generated using the pch-pads-parser utility [2]. The inteltool dump
before and after the patch is identical (see notes)
Notes:
1. For some reason, GPIO RX State (RO) for the GPP_F4 and GPP_G10
changed the value to 0, but this doesn't affect the motherboard
operation. Perhaps this is because PAD_CFG1_GPIO_DRIVER is set to
PAD_CFG_GPI_INT(), and the pad is not actually connected. So far I
haven't circuit diagram to check this out.
2. According to the documentation [1], the value 3h for RXEVCFG is
implemented as setting 0h.
3. If the available macros from gpio_defs.h [3] can't determine the
configuration of the pad, the utility [2] generates common
_PAD_CFG_STRUCT() macros
