In an effort to reset the DP controller states on a disconnect, the
driver is issuing a SW reset to the controller. But SW reset on
the controller doesn't necessarily restore the controller to its
full reset state. It only resets part of the logic. So if for some
reason the MST streams were not disabled properly, ie. the slot
allocations were not reset properly in the controller, then a SW
reset would result in the DP controller raising state interrupts.
Since this SW reset is issued in the tail end of the disconnect
processing, the driver turns off all the clocks and also
removes the irq handler. This results in an interrupt storm at
the MDSS top level.
This change removes the SW reset on the disconnect path and
relies on the SW reset that already exists in the connect path
to restore controller state.

MST driver is incorrectly using maximum bw_code while initializing
MST topology manager instead of maximum link clock in KHz. This
prevents the topology manager to set MST state on a subsequent MST
plug in causing all MST cases to fail.

During link training, after the swing/preemphasis is updated, the driver
is supposed to poll the link status on the sink and quit once the
LINK_STATUS_UPDATED bit is set and also latch the next set of
swing/preemphasis requested by the sink. But currently, the driver is
exiting the loop only when the LINK_STATUS_UPDATED bit is cleared. So,
it also latches the swing/emphasis request from the second read.
Typically, the SW read is slow enough that the bit is set on the first
read. The driver then reads the second time and exits the loop, since
the bit would be cleared then. In most cases, this doesn't affect
the training sequence, since the swing/preemphasis request for next
attempt is retained on the second read. But, atleast in one
specific case, it was observed that the swing/emphasis request
gets reset along with LINK_STATUS_UPDATED and so the driver ends
up missing the actual request and latches incorrect values instead.
This causes link training to fail as it keep retrying with the
same values that it starts with.
This change fixes the exit condition check so the driver quits the loop
as soon as the LINK_STATUS_UPDATED bit is set.

Decouple the configuration and parsing of aux switches with the
parsing and configuration of HPD sources. HPD notification can come from
either GPIO based approach or a PD module through a SW interface. The
presence of AUX switch on the board should have no bearing in deciding
which configuration for HPD detection is used. Update the implementation
to allow for flexibility in selecting any combination of the HPD source
and aux switches.

Use #if IS_ENABLED() instead of #ifdef for configurations as vendor module
guidelines.
Use #if IS_ENABLED(CONFIG_XXX) instead of #ifdef CONFIG_XXX to ensure that
the code inside the #if block continues to compile if the config changes
to a tristate config in the future.
The differences are as follows:
1.#if IS_ENABLED(CONFIG_XXX) evaluates to true when CONFIG_XXX is set to
module (=m) or built-in (=y).
2.#ifdef CONFIG_XXX evaluates to true when CONFIG_XXX is set to
built-in(=y) , but doesn't when CONFIG_XXX is set to module(=m).
Use this only when you're certain you want to do the same thing
when the config is set to module or is disabled.
