Add support for compiling Airoha ATF, based on a modified version of the
TF-A based on 2.10.
The package will clone the base TF-A and apply the modified source and
pre-compiled objects (DDR calibration, eFUSE handling, TX/RX path...) to
correctly compile.
An helper script is added to implement the same format used for special BL2
handling. BL2 is composed of 3 sub-phase with a initial BL21, a BL22 that
loads a LZMA decompressor and BL23 that actually calibrate and loads BL31
ATF.
Also a special flash_table is used to handle SPI-NAND externally to the
BL2, a special Host target is added for that.
