Update the spi_nor_read() function based on the config SPI_FLASH_BAR
and update the length and bank calculation by spliting the memory of
16MB size banks only when the address width is 3byte.
Fix the read issue for 4byte address width by passing the entire
length to the read function.

While we want to compile the SPI_STACKED_PARALLEL code everywhere we
can, it must first be guarded with an #if for DM_SPI as not all cases
where we have this code built, such as in SPL, will have the relevant
DM_SPI option enabled.

Prevent the code gated by SPI_STACKED_PARALLEL from bitrot
by using if (CONFIG_IS_ENABLED(SPI_STACKED_PARALLEL)) around
it. That way, it is always at least compiled.

The SPI_ADVANCE description does not explain what the switch does.
It does not have anything to do with any advanced functionality, it
only gates off support for stacked and parallel SPI NORs. Rename the
Kconfig symbol, update description, and move it right next to Xilinx
hardware as it seems to be specific to this hardware. Make sure the
symbol is also protected by if DM_SPI in Kconfig.
