hv: debug: add the hypervisor NPK log

Browse Source 
The npk_log is a log destination for the hypervisor, similar to the
console_log and the mem_log. It can be enabled/disabled/configured
by the SOS kernel via the hypercall HC_SETUP_HV_NPK_LOG.
The configuration includes:
1. Set the MMIO base address of the reserved NPK master.
2. Set the log level of the hypervisor NPK log.
After that, the npk_log can be enabled to write the hypervisor logs to
the MMIO address of the reserved NPK master with a simple header.
