The psp_notify_boot_done call is done at the entry of BS_PAYLOAD_BOOT,
so it's not guaranteed that the psp_set_spl_fuse call is done before the
psp_notify_boot_done call. Moving the psp_set_spl_fuse call makes sure
that it's done before the psp_notify_boot_done call. This also brings
the psp_set_spl_fuse call in line with the enable_secure_boot call that
sends the PSB fusing command to the PSP.

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.

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.
