This patch enables the Microchip's FPGA QSPI and Polarfire SoC QSPI controller support.
Tested spi-nand (W25N01GV) and spi-nor (MT25QL256A) on Microchip's ICICLE kit. tested using both FPGA QSPI and Polarfie SoC QSPI.
changes in v2 ------------ 1. Replaced spi_alloc_master() with devm_spi_alloc_master() 2. Used dev_err_probe() when devm_spi_alloc_master() fails. 3. Added shared IRQ flag in the interrupt registration. 4. Updated the dt_bindings so that there is a differentiation between FPGA QSPI IP core and hard QSPI IP core. 5. Updated the MAINTAINERS file.
