Currently, driver is determining the amount of memory to allocate
based on the event log object indexes (first, last). The last index
can change if there is additional logging done during the coredump
phase and potentially cause an out-of-bound memory access during
buffer traversal.
This change restrict the event log object traversal to a maximum
of the output buffer size.

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.

Currently, SDE_DBG_DUMP takes any number of hw block names along with
few defined strings as arguments. This set of arguments is used to
determine which HW block registers needs to be dumped. Move to a
blk bitmask to avoid passing a large set of arguments. The bitmask is
split based on the clks required to access the HW block for ease of use.
The lower 0-23 bits are used for HW blocks which can be accessed by just
enabling the MDP clks. DP is kept separate as it needs DP specific
clks to be enabled. Add a debugfs node through which the mask can be
modified, which can be useful while using the debugfs dump option to
force a panic.
As part of the change, remove in-log/in-mem enable mask debugfs node
for every debugbus and use a single node to control the logging
mechanism for all the HW blocks debugbus.
