Update spi drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.
We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.

This patch adds driver for the Microchip Polarfire SOC MSS QSPI
controller.
The interrupts of the MSS QSPI are routed through PLIC(Platform level
interrupt controller).
Tested with generic spi-nor flash driver(spi_flash) with both Fixed
flash configuration and Read flash parameters at runtime(using SFDP).
