Poky migration from rocko to warrior

Note 1

• /dev/xdevfg got obsolete - there's fpga manager instead which cannot load *.bit (only *.bin or *.bit.bin)
• Solution:

Brought back the old driver (drivers/char/xilinx_devcfg.c)- it works

Note 2

• php 5.6.40 - EOL and won't build
• Solution:

Disabled mysql extension:
To meta-elphel393/recipes-devtools/php/php_5.6.%.bbappend:
    PACKAGECONFIG[mysql] = "--without-mysql --without-mysqli --without-pdo-mysql"
    CFLAGS += " -ldl"
