SPI flash: Fix alignment checks in Page Program commands

There are two separate restrictions to take into account:

  Page Program command must not cross address boundaries defined by the
  flash part's page size.

  Total number of bytes for any command sent to flash part is restricted
  by the SPI controller capabilities.

Consider

  CONTROLLER_PAGE_LIMIT=64, page_size=256, offset=62, len=4.
  This write would be split at offset 64 for no reason.

Consider

  CONTROLLER_PAGE_LIMIT=40, page_size=256, offset=254, len=4.
  This write would not be split at page boundary as required.

We do not really hit the second case. Nevertheless, CONTROLLER_PAGE_LIMIT
is a misnomer for the maximum payload length supported by the SPI controller
and is removed in a followup.

AMD SPI: Optimise for longer writes

Leave it to the implementation of flash->write() to split the writes
to match SPI controller and SPI flash part restrictions. This allows
for some optimisation for auto-address-increment (AAI) commands.

Kconfig AMD_SB_SPI_TX_LEN can be kept as local.

AGESA: Fix error status code return type to enum from UINT32

AGESA correctly uses the enum AGESA_STATUS type whereas boards use a
mess of UINT32 typecasts.

Also no need to shout VOID. We are not that careful on changing
all cases of VOID->void or whitespace issues as these files will
get merged with follow-ups.
