Rather than printing random garbage from stack and pretending that it is
the default safe_to_exit_level, set the variable beforehand.

The msm_dp_utils_pack_sdp_header() accepts an unlimited-size u32 pointer
for the header output, while it expects a two-element array. It performs
a sizeof check which is always true on 64-bit platforms (since
sizeof(u32*) is 8) and is always falce on 32-bit platforms. It returns
an error code which nobody actually checks.
Fix the function interface to accept u32[2] and return void, skipping
all the checks.

The msm_dp_panel_dump_regs() and msm_dp_catalog_dump_regs() are not
called anywhere. If there is a necessity to dump registers, the
snapshotting should be used instead. Drop these two functions.

Having I/O regions inside a msm_dp_catalog_private() results in extra
layers of one-line wrappers for accessing the data. Move I/O region base
and size to the globally visible struct msm_dp_catalog.

Move CTRL-related functions to dp_ctrl.c, inlining one line wrappers
during this process. The enable/disable functions have been split to the
enable/disable or enter/exit pairs. The IRQ and HPD related functions
are left in dp_catalog.c, pending later cleanup.

programmed earlier.

done by the rest of the submodules. Inline functions with simple
register access patterns.

All other submodules pass arguments directly. Drop struct
msm_dp_panel_in that is used to wrap dp_panel's submodule args and pass
all data to msm_dp_panel_get() directly.
