platform/mellanox: mlxbf-pmc: Ignore unsupported performance blocks
Currently, the driver has two behaviors to deal with new & unsupported
performance blocks reported by the firmware:
1. For register and unknown block types, the driver will fail to load
with the following error message:
[ 4510.956369] mlxbf-pmc: probe of MLNXBFD2:00 failed with error -22
2. For counter and crspace blocks, the driver will load and sysfs files
will be created but getting the contents of event_list or trying to
setup the counter will fail
Instead, let's ignore and log unsupported blocks. This means the driver
will always load and unsupported blocks will never show up in sysfs.
