uboot-lantiq: vrx200 - lzma compress gphy firmware

Browse source 
The default bootloader partition of some devices is to small for an
u-boot with uncompressed gphy firmware(s).

Instead of increasing the bootloader partition size, in compare to the
stock firmware, compress the firmware. This would allow the bootloader
of at least the FritzBox 3370 as well as the bootloader of the
VGV7510KW22 to fit into the bootloader partition of the stock firmware.
