Add support for the Cadence QSPI controller. This controller is
present in the Intel Lightning Mountain(LGM) SoCs, Altera and TI SoCs.
This driver has been tested on the Intel LGM SoCs.
This driver does not support generic SPI and also the implementation
only supports spi-mem interface to replace the existing driver in
mtd/spi-nor/cadence-quadspi.c, the existing driver only support SPI-NOR
flash memory.
I am finally able to get spi-mem based cadence-quaspi driver working on
TI platforms with DMA and DAC mode. I have also incorporated changes to
disable DAC and autopolling for your intel SoC:
Thanks! a lot for the confirmation, with your changes it is working on
TI platform.

(Top two patches are of interest)
I have tested both DAC and INDAC mode with s25fl flash and everything
seems to be fine. Could you re test the driver on your SoC?
while re-testing QSPI_NOR/NAND both didn't work, after few changes from
patchV6 followed by your changes,
now QSPI-NOR started working, soon will be sending updated patch
version which includes your changes as well as my changes
without affecting both the platforms(TI and Intel).
BTW, Have you tested QSPI-NAND on your platform ? with our patches.
Thanks! for your review and support.

Feel free to
fold it into your series if everything works.
sure, I will test on Intel SoC with your changes .
