p54spi: Kconfig option for config blob

This patch adds an Kconfig option, which allows the user
to select, whenever he/she wants to include a 4k blob for
generic calibration and interface values into the driver,
or cut the module size by about 15 to 20%.

+         a dedicated EEPROM chip to store all device specific values

+         Enabling this option adds about 4k to p54spi.
