mpc85xx: disable kernel uImage generation

Browse Source 
The previous workaround for the unsupported mkimage xz compression
leads to the TP-Link TL-WDR4900s simpleImage bootwrapper being gzip
compressed, which does not fit the kernel partition.

Removing the uImage gerneration works around this problem.

Subject: [PATCH] powerpc: bootwrapper: disable uImage generation
Due to CONFIG_KERNEL_XZ symbol, the bootwrapper code tries to
instruct the mkimage to use the xz compression, which isn't
supported. This disables the uImage generation, as OpenWrt
generates individual uImages for each board using it's own
toolchain.

Subject: [PATCH] powerpc: bootwrapper: force gzip as mkimage's compression
method
Due to CONFIG_KERNEL_XZ symbol, the bootwrapper code tries to
instruct the mkimage to use the xz compression, which isn't
supported. This patch forces the gzip compression, which is
supported and doesn't matter because the generated uImage for
the apm821xx target gets ignored as the OpenWrt toolchain will
do separate U-Boot kernel images for each device individually.
