[PATCH v2] i3c: master: amd: Report direct CCC read length in payload.actual_len

[Shubham Patil]

The I3C core expects master drivers to leave payload.len unchanged and
report the number of bytes received on GET CCCs via payload.actual_len.
The AMD driver was overwriting payload.len after direct read CCCs.

Set payload.actual_len from the directed command's rx_actual in
xi3c_master_send_direct_ccc_cmd() instead of modifying payload.len.

I3C master controller")
