x86: coreboot: Add generic coreboot payload support
Currently building U-Boot as the coreboot payload requires user
to change the build configuration for a specific board during
menuconfig process. This uses the board's native device tree
to configure the hardware. For example, the device tree provides
PCI address range for the PCI host controller and U-Boot will
re-program all PCI devices' BAR to be within this range. In order
to make sure we don't mess up the hardware, we should guarantee
the range matches what coreboot programs the chipset.
But we really should make the coreboot payload support easier.
Just like EFI payload, we can create a generic coreboot payload
for all x86 boards as well. The payload is configured to include
as many generic drivers as possible. All stuff that touches low
level initialization are not allowed as such is the coreboot's
responsibility. Platform specific drivers (like gpio, spi, etc)

While at simplifying things, use '\0' instead of NULL when adding an
empty char at the end of the buffer.

tpm: sandbox: fix wrong check on pcr_map
The second check on pcr_map in sandbox_tpm2_xfer() is wrong. It should
check for pcr_map not being empty. Instead, it is a pure copy/paste of
the first check which is redundant.
This has been found thanks to a Coverity Scan report:
CID 183370: Memory - illegal accesses (UNINIT)
Using uninitialized value "pcr_index".
put_unaligned_be32(tpm->pcr_extensions[pcr_index], recv);
This is because pcr_index is initialized only if the user input is
correct, ie. at least one valid bit is set in pcr_map.
Fix the second check and also initialize pcr_index to 0 (which is
harmless in case of error) to make Coverity Scan happy.

db410: alter WLAN/BT MAC address fixup
Change the way MAC address fixup is done:
1. Stop using LK handed device-tree and calculate
the MAC address our own.
2. Allow overriding the generated MACS with environment variables:
"wlanaddr" and "btaddr".
