mpc85xx-p1010: add Kernel 5.10 support

Tested on: Sophos RED 15W

The TP-Link WL-WDR4900 needs to be disabled when 5.10 becomes the
default kernel.

When building with all kmods enabled, the resulting kernel image
exceeds the maximum size the bootloader reads from the flash.

For more information, see GitHub issue #1773

+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.
