Add assert to make sure the level is a legal value.

The rom layout for A/B recovery:
EFS -> PSP L1 0x48 -> PSP L2 A -> BIOS L2 A
0x4A -> PSP L2 B -> BIOS L2 B
The coreboot doesn't implement the AMD's A/B recovery. This is only
for the ROM layout. To save some flash space, the entire B section can
be eliminated.
To enable A/B recovery in PSP layout, add "--recovery-ab" to
amdfwtool.

Address Mode 0: Physical Address, bit 63~56: 0x00
Address Mode 1: Relative Address to entire BIOS image, bit 63~56: 0x40
Address Mode 2: Relative Address to PSP/BIOS directory, bit 63~56: 0x80
Address Mode 3: Relative Address to slot N, bit 63~56: 0xC0
It is the expanding mode for simple relative address mode, for which
address_mode equals 1.
Only mode 2 is added. We need to record current table base address and
calculate the offset. The ctx.current_table is zero outside the
table. When it goes into the function to integrate the table, it
should backup the old value and get current table base. Before it goes
out the function, it should restore the value.
If the table address mode is 2, the address in each entry should be
also add address mode information. If not, the address mode in entry
is meanless.
The old mode 0,1 should be back compatible.

The second generation EFS (offset 0x24[0]=0) uses "binary relative"
offsets and not "x86 physical MMIO address" like gen1.
The field additional_info in table header can tell if the absolute or
relative address is used.
Chips like Cezanne can run in both cases, so no problem
comes up so far.
The related change in psp_verstage has been uploaded.

The relative mode is the mode 1 of four address modes. The absolute
mode is the mode 0. Later we will implement mode 2. Not sure if mode 3
is needed.
It needs to be simple to work with psp_verstage change to make SOC
Cezanne work quickly. This patch is defacto a subset of
https://review.coreboot.org/c/coreboot/+/59308
which implements the framework of address mode and covers mode
0,1,2. Some hardcode value like 29 can be removed in 59308.

In 58555, we added the SOC ID for Stoneyridge in amdfwtool
command line. But it raised building error because it then called
"set_efs_table" without setting SPI mode. So we skipped calling that.
But in set_efs_table, it has case for Stoneyridge. The boards also
need to have this setting. So we remove the skipping and give the
proper SPI mode in mainboard Kconfig.

The element at offset 0x14 in the embedded_firmware struct is the
pointer to the combo PSP directory header, so rename it from comboable
to combo_psp_directory to clarify that this is not a flag, but a pointer
to a data structure. Also rename psp_entry to psp_directory since it
points to the PSP directory table.

The value of level defined in table is the default one. We now give an
extra option in config file to change this value so some FWs can be
dropped in a more optimized way.
For the non A/B recovery mode, The value could be L1, L2, Lb or Lx,
which are level 1, leve 2, level both and using default value. If it
is empty or Lx, left the level in table unchanged.
Give a redundant field [12bxBX] in regular exprssion for A/B recovery
which will be done later.

The DWORD used to indicate the Embedded Firmware Structure's generation
uses 1 to indicate a first-gen structure, e.g. a SPI device's erased
value of 0xffffffff. A 0 in bit 0 is how Client PSPs will interpret
the structure as designed for second-gen.
This change and the original addition should have no effects on
any current products as none interpret offset 0x24.
