The hv_24×7 feature in IBM® POWER9™ processor-based servers provide the
facility to continuously collect large numbers of hardware performance
metrics efficiently and accurately.
This patch adds hv_24x7 metric file for different Socket/chip

EASRC (Enhanced Asynchronous Sample Rate Converter) is a new IP module

The primary features for the EASRC are as follows:
- 4 Contexts - groups of channels with an independent time base
- Fully independent and concurrent context control

There is a new ASRC included in i.MX serial platform, there
are some common definition can be shared with each other.
So move the common definition to a separate header file.
And add fsl_asrc_pair_priv and fsl_asrc_priv for
the variable specific for the module, which can be used
internally.
In order to move common structure to fsl_asrc_common.h
we change the name of asrc_priv to asrc, the asrc_priv
will be used by new struct fsl_asrc_priv.
