drm/xe/debugfs: Don't expose dgfx residencies attributes on VF

In addition of checking if we are running on the BATTLEMAGE,
we should also check for not being a VF driver, as VFs can't
access necessary registers, and doing so leads to:

 | .. [drm] GT0: VF is trying to read an inaccessible register 0x35b004+0x0
 | RIP: 0010:xe_gt_sriov_vf_read32+0x5e2/0x8a0 [xe]
 | Call Trace:
 |  xe_mmio_read32+0x110/0x280 [xe]
 |  read_residency_counter+0x42/0xd0 [xe]
 |  dgfx_pkg_residencies_show+0x115/0x190 [xe]
 | .. [drm] Package G2 counter failed to read, ret -19

or

 | .. [drm] GT0: VF is trying to read an inaccessible register 0x35b004+0x0
 | RIP: 0010:xe_gt_sriov_vf_read32+0x5e2/0x8a0 [xe]
 | Call Trace:
 |  xe_mmio_read32+0x110/0x280 [xe]
 |  read_residency_counter+0x42/0xd0 [xe]
 |  dgfx_pcie_link_residencies_show+0xe7/0x160 [xe]
 | .. [drm] PCIE LINK L0 RESIDENCY counter failed to read, ret -19

Similarly, there is no point to expose inject_csc_hw_error on VFs,
as HW errors support is already disabled for VFs.
