The current implementations of edid_read() and segments_edid_read() have
a few problems:
1. The type of variable `c` is incorrect, not matching the return type
of sp_tx_aux_rd(). In addition, the meaning of `c` is unknown.
2. It is pointless to do `cnt++` when sp_tx_aux_rd() fails.
3. These two functions ignore the return value of
anx7625_reg_block_read().
4. In segments_edid_read(), anx7625_reg_write() might return a positive
value on failure.
Fix all of the 4 issues, and modify the code to be closer to kernel
5.10's implementation (drivers/gpu/drm/bridge/analogix/anx7625.c). Note
that, however, unlike in kernel, anx7625_reg_block_read() here doesn't
return the number of bytes. On success, 0 is returned instead.
In addition, following coreboot's convention, always return negative
error codes. In particular, change the return value to -1 for
edid_read() and segments_edid_read() on failure.

This patch adds a new ..._unverified_area_... group of functions to the
cbfs_map/_load/_alloc() APIs. These functions can be used to access
custom FMAP sections and are meant to replace the existing
cbfs_locate_file_in_region(). The name is intended to highlight that
accesses through this API will not be verified when CBFS_VERIFICATION is
enabled and should always be treated as if they may return malicious
data. (Due to laziness I'm not adding the combination of this API with
the ..._type_... variant at this point, since it seems very unlikely
that we'll ever have a use case for that. If we ever do, it should be
easy to add later.)
(Also remove the 'inline' from cbfs_file_hash_mismatch(). I'm not sure
why I put it there in the first place, probably a bad copy&paste.)

When using 32 bit PCI accesses in lpc_enable_port80, we can use the
LPC_IO_OR_MEM_DECODE_ENABLE and DECODE_IO_PORT_ENABLE4 defines and don't
need to re-define bits with offsets from the beginning of the third byte
within this 32 bit register. This allows to drop the
LPC_IO_OR_MEM_DEC_EN_HIGH register definition which points to
LPC_IO_OR_MEM_DECODE_ENABLE + 2 and to drop the re-definitions of the
bit re-definitions with a different offset.
The code in lpc_enable_port80 was originally copied from sb/amd/agesa/
hudson/early_setup.c which might be sort-of a copy from what the AGESA
reference code does.

The patch enables cse_fw_sync() before DRAM initialization.
cse_fw_sync() sends HECI commands in order to set CSE's boot partition
and to trigger CSE firmware update.
As part of CSE firmware update, coreboot sends HMRPFO_ENABLE HECI
command. Since CSE supports the command after DRAM Initialization,
cse_fw_sync() is called after DRAM initialization.
Starting from CSE Litev16.0.15.1545, CSE support HMRFPO_ENABLE command
before DRAM initialization too. So, cse_fw_sync() is called before DRAM
initialization.
