gpu: nova-core: don't print raw PMU table entries

Browse Source 
Remove the (large) raw form of the PMU table entries. The resulting
PMULookupTable is still getting printed (in more useful form) later,
anyway, so this was redundant, even for debugging. This output (the
example is from an Ampere GPU) is what is being removed:

NovaCore 0000:e1:00.0: PMU entry: [01, 01, 54, 54, 01, 00]
NovaCore 0000:e1:00.0: PMU entry: [00, 00, 00, 00, 00, 00]
NovaCore 0000:e1:00.0: PMU entry: [00, 00, 00, 00, 00, 00]
NovaCore 0000:e1:00.0: PMU entry: [00, 00, 00, 00, 00, 00]
NovaCore 0000:e1:00.0: PMU entry: [00, 00, 00, 00, 00, 00]
NovaCore 0000:e1:00.0: PMU entry: [07, 06, e0, b7, 03, 00]
NovaCore 0000:e1:00.0: PMU entry: [08, 01, bc, 56, 05, 00]
NovaCore 0000:e1:00.0: PMU entry: [00, 00, 00, 00, 00, 00]
NovaCore 0000:e1:00.0: PMU entry: [45, 07, 88, da, 01, 00]
NovaCore 0000:e1:00.0: PMU entry: [85, 07, 34, c9, 02, 00]
NovaCore 0000:e1:00.0: PMU entry: [49, 05, 7c, b3, 04, 00]
NovaCore 0000:e1:00.0: PMU entry: [89, 05, 1c, 05, 05, 00]
NovaCore 0000:e1:00.0: PMU entry: [00, 00, 00, 00, 00, 00]
NovaCore 0000:e1:00.0: PMU entry: [00, 00, 00, 00, 00, 00]
NovaCore 0000:e1:00.0: PMU entry: [00, 00, 00, 00, 00, 00]
NovaCore 0000:e1:00.0: PMU entry: [00, 00, 00, 00, 00, 00]

And it is immediately followed by a more useful, interpreted list of
selected PMU table data, which is *not* being removed as part of this
commit. That looks like this:

NovaCore 0000:e1:00.0: PmuLookupTableEntry desc: FalconUCodeDescV3 {

}
