Marvell/Drivers: MvSpiFlash: Enable dynamic SPI Flash detection
Hitherto mechanism of fixing SPI flash model in the PCDs,
occured to be very inefficient and problematic. Enable
dynamic detection by reworking MvSpiFlashReadId() command,
which now uses newly added NorFlashInfoLib, that helps to
obtain description of the JEDEC compliant devices.
This patch updates the MvSpiFlashProtocol ReadId() protocol
callback on both producer's (MvFlashDxe) and consumers' sides
(FirmwareUpdate and SpiTool applications). Because all
information about detected SPI NOR flash is now stored in
the obtained NorFlashInfo structure fields, use them instead
of the PCDs.
Enable compilation of the NorFlashInfoLib and update
PortingGuide documentation accordingly.
