[PATCH 1/2] media: iris: enable pipe for hfi gen2 encoder

[Sachin Kumar Garg <sachin.garg@oss.qualcomm.com>]

Currently the PIPE capability (HFI_PROP_PIPE / work-route) is only
wired up for the HFI Gen2 decoder. Add a PIPE entry to the HFI Gen2
encoder instance capability table, and extend the encoder
branch of iris_session_init_caps() to derive PIPE's min/max/value
from the platform's num_vpp_pipe, mirroring the existing decoder
handling.
