This removes all the duplicated code and logic and leverages
the existing ones in libraries themselves. The current side
effect is that protection cannot be fully enabled because the
read, write, and write enable command are not exposed in struct
spi_flash currently. That support can be revised if protection
scheme makes sense for our use-cases once it's better understood.

All solid state devices have vendor id defined by JEDEC specification JEP106,
which originally allocated only 7 bits for it plus parity. When number of
vendors exploded beyond 126, a banking proposition came maintaining
compatibility with older vendors while allowing for 4 extra bits (16 banks)
through the introduction of the concept "Continuation code", denoted by the
byte value of 0x7f.
Examples:
0xfe, 0x60, 0x18, 0x00, 0x00 => vendor 0xfe of bank o
0x7f, 0x7f, 0xfe, 0x60, 0x18 => vendor 0xfe of bank 2

Use the new SPI code from common folder, delete spi.c. SPI related macros
must be single defined, in southbridge.h if they are used by files other
than the common SPI code, fch_spi.h if they are only used by the common
SPI code. The only exception is SPI_FIFO_DEPTH which must be in southbridge.h,
because it can change between SOC.

TEST=Build and boot grunt using new SPI code, with debug enabled. Check
output.

Create a new SPI code that overrides flash operations and uses the SPI
controller within the FCH to its fullest.
