xilinx: cmd: Add support for FRU commands This patch adds support for fru commands "fru capture" and "fru display". The fru capture parses the FRU table present at an address and stores in a structure for later use. The fru display prints the content of captured structured in a readable format. As of now, it supports only common header and board area of FRU. Also, it supports only English language code and ASCII8/BINARY formats. fru_data variable is placed to data section because fru parser can be called very early before bss is initialized. And also information needs to be shared that's why it is exported via header.

xilinx: cmd: Add basic fru format generator Idea is to have something what can be used for board bringup from generic board perspective. There is a violation compare to spec that FRU ID is ASCII8 instead of binary format but this is really for having something to pass boot and boot to OS which has better generating options. Also time should be filled properly. For example: fru board_gen 1000 XILINX versal-x-prc-01-revA serialX partX There is also support for revision field which is Xilinx specific field.

fru: common: Switch capture variable with the rest capture variable is bool which is just one byte and it is just causing unaligned accesses. Better to have it as last entry in the structure.
