HACK: arm64: add CNTPCT_EL0 trap handler

The upstream kernel deliberately blocks EL0 access to CNTPCT.  However
Qualcomm's time_daemon attempts to read from CNTPCT_EL0, and Qualcomm
has forked the ARM architectured timer driver to allow this to succeed.

As a workaround, add a trap handler for CNTPCT similar to the existing
one for CNTVCT.
