Existing FPGA program write is always assume RBF data >= 32 bytes, so
any rbf data less than 32 bytes writing to FPGA would be failed.
This patch enhances the FPGA program write to support rbf data with
size >= 4 bytes.

Move FPGA driver which is Gen5 specific code into Gen5 driver file
and keeping common FPGA driver intact. All the changes are still keeping
in driver/fpga/ and no functional change. Subsequent patch would move
FPGA manager driver from arch/arm into driver/fpga/.

Add CX9020 board based on mx53loco.
Add simplified imx53 base device tree from kernel v4.8-rc8, to reuse
serial_mxc with DTE and prepare for device tree migration of other
functions and imx53 devices.
The CX9020 differs from i.MX53 Quick Start Board by:
- use uart2 instead of uart1
- DVI-D connector instead of VGA
- no audio
- CCAT FPGA connected to emi
- enable rtc

This patch adds support for programming of the StratixV FPGAs. Programming
is done in this case (board theadorable) via SPI. The board may provide
board specific code for bitstream programming.
This StratixV support will be used by the theadorable board.

Apparently, the logic for the FPGA global bit is not universal between Gen5
and Gen10 devices is not the same. Disabling this bit, while applicable to
Gen10 devices, will break FPGA programming on Gen5 devices.

The sandbox/ext4/fat/generic fs commands do not gracefully deal with files
greater than 2GB. Negative values are returned in such cases.
To handle this, the fs functions have been modified to take an additional
parameter of type "* loff_t" which is then populated. The return value
of the fs functions are used only for error conditions.

When ARCH_DMA_MINALIGN is greater than header size of the bit file, and buf is
not aligned, new_buf address became greater then buf_start address and the
load_word loop corrupts bit file data.
A work around is to decrease new_buf of ARCH_DMA_MINALIGN, it might corrupt data
before buf but permits to load correctly.
