Update interface of memc flexspi driver to better handle multiple
devices. Previously, using multiple devices on one FlexSPI bus would
require the user to configure each device to install its command table
(referred to as a LUT table by the driver) at an offset, so that it did
not overlap with other devices on the bus.
This commit changes the interface of the memc flexspi driver to instead
configure the LUT and flash device in one call. This allows the memc
driver to record the port each LUT sequence is used with, so that
future FlexSPI transfer requests can have their LUT offsets adjusted
based on the target port (which will correspond to a target device)

Introduce driver for APS6408L PSRAM, built on top of the MCUX memc
driver for flexSPI. This driver supports operating the PSRAM in high
speed mode (200MHz or more). Note that in order to support this
PSRAM's alignment requirements, either ahb-read-addr-opt or
ahb-prefetch must be set for the FlexSPI instance.
