lantiq: fix 0008-MIPS-lantiq-backport-old-timer-code.patch for Amazon-SE

The patch 0008 removes the vanilla kernel gptu.c of lantiq.
But the replacement file timer.c does not work Amazon-SE and
is also protected therefore with an CONFIG_SOC_AMAZON_SE :-)

This commit will re-activate the default vanilla kernel code
in gptu.c for Amazon-SE.
