Checking whether a pointer is NULL after it has been dereferenced makes
zero sense. Make sure the `wifi_ssdt_write_properties()` function never
gets invoked with a NULL argument for the `dev` parameter, and simplify
the logic around the `is_cnvi_ddr_rfim_enabled` variable accordingly.

Chause doesn't get to x86 bootblock without the SPL table binary in the
PSP directory table, so I assume that Majolica won't get to x86
bootblock either, since the Cezanne SoC default is not to include any
SPL table binary. This was caused by a combination of
commit 6c5ec8e31c (amdfwtool: Add options
to support mainboard specific SPL table) that caused a regression in
amdfwtool and commit c5b912f788
(soc/amd/cezanne: Allow to specify SPL table path in Kconfig) that
removed the default for the Cezanne SoC. Fix this by adding the default
SPL table file back to the fw.cfg file which will get ignored by
amdfwtool when a mainboard selects SPL_TABLE_FILE and specifies another
SPL table binary.

This patch removes different implementation to cache the SPI ROM between
early and later boot stage where SPI ROM caching doesn't need even
advanced implementation like `mtrr_use_temp_range()` as SPI ROM ranage

can be sufficient without any additional complexity.

Since Sabrina uses the image slot header (ISH) that depends on the AMD
A/B recovery scheme that depends on the multi-level PSP directory
support, the multi-level support gets automatically selected by passing
Sabrina as SoC name to amdfwtool, so passing the --multilevel command
line switch to amdfwtool isn't needed.
TEST=Timeless build results in identical binary for chausie

The fch_i23c_pad_init implementation was written without looking at any
reference code and turned out to not work properly on hardware. Before
this function writes to the MISC_I23C_PAD_CTRL registers, the value read
back is 0x3000003c which results in the I2C bus communication to work
while the 0x300003fc the code writes to the register breaks the I2C
communication. Removing the code that sets bits 6..9 fixes the I2C bus
communication.

Contradicting the PPR #57243 version 1.56, the I2C3 pad control register
in the MISC ACPIMMIO region is the same new I23C pad type as the
corresponding registers for I2C0..2 and not the older I2C pad control
register type used on Picasso and Cezanne. All I2C pads being of the new
I23C type is in line with the GPIOMUX settings for the pins used by
I2C0..3 that can alternatively connect the pins to an I3C controller.

We set T3 as 300ms to meet Elan's spec, but the resume/suspend times
are greater than 500ms, which is the spec for Chromebooks.
The actual kernel timing has been measured, and given the ACPI delay
after deasserting reset in addition to the delay until the kernel
driver accesses the device, delaying only 200ms in the ACPI method is
also sufficient to meet the 300ms requirement.

C1 has a redriver which does SBU muxing, so disable SBU muxing in the
SoC. However, this also disables AUX biasing when the pins are
