drm/amd/display: fix resume hang because of DP short pulse

There is a hard hang observed during resume from S3 when
the system receives a DP short pulse interrupt. This is
because there are two code paths contending for GPIO
access for AUX channel transactions. One such path is
through amdgpu_dm_display_resume() function which is
invoked from the regular system resume code path. The
other path is through handle_hpd_rx_irq(), which is
invoked in response to system receiving DP short pulse
interrupt. handle_hpd_rx_irq() guards against conflicting
GPIO access using hpd_lock, but the GPIO access from
amdgpu_dm_display_resume() remains unguarded.

This patch makes sure we use hpd_lock inside
amdgpu_dm_display_resume() to avoid race conditions
for GPIO access.

drm/amd/display: make dc_commit_surfaces_to_stream() re-entrant

dc_commit_surfaces_to_stream() function currently
is handle's only one plane at a time.
This will not work if multiple planes have to be set to a crtc.

The functionality of dc_commit_surfaces_to_stream() with this patch
is slit into
1. Accumulate and initialise all the surfaces that needs to be
   set to a crtc.
2. Update the intialised set of surfaces to the steam in one go.

Hence dc_commit_surfaces_to_stream() is renamed to init_surfaces().
Once all the planes requested by user space are initialised,
dc_commit_surfaces_to_stream() shall sequentially populates *updates,
 *flip_addr, *plane_info and *scaling_info for all surfaces.
