vdpa/octeon_ep: Fix format specifier for pointers in debug messages

Updates the debug messages in octep_vdpa_hw.c to use the %p format
specifier for pointers instead of casting them to u64.

Fixes smatch warning:
octep_hw_caps_read() warn: argument 3 to %016llx specifier is cast
from pointer

Fixes: 8b6c724 ("virtio: vdpa: vDPA driver for Marvell OCTEON DPU devices")
