3d95688c85 x86: Panic when SPL or TPL fail
At present when these fail to boot there is no message, just a hang. Add a
panic so it is obvious that something when wrong.

daade119aa x86: spl: Reduce priority of the basic SPL image loader
This image loader works on systems where the flash is directly mapped to
the last part of the 32-bit address space. On recent Intel systems (such
as apollolake) this is not the case.

Reduce the priority of this loader so that another one can override it.

While we are here, rename the loader to BOOT_DEVICE_SPI_MMAP since
BOOT_DEVICE_BOARD is not very descriptive.

14dd93beb7 x86: spl: Use hang() instead of a while() loop
Use the standard hang() function when booting fails since this implements
the defined U-Boot behaviour for this situation.

7c03caf6fa x86: Add a simple TPL implementation
Add the required CPU code so that TPL builds correctly. Also update the
SPL code to deal with being booted from TPL.
