Separate core watchdog functionality from the qcom watchdog
driver to create a framework for other qcom watchdogs. This
will reduce the duplication of code for future watchdog
drivers and allow them to take advantage of this framework.

In preparation to change the qcom watchdog to a new core
framework that future watchdog drivers will utilize, the name
of the file needs to be changed. Due to the number of changes
needed in the file we need to rename it to reflect its new purpose.

By default, the ramdump driver expects the virtual address of the
segments to be set in order to collect the dumps. However, the
minidump collection path in the PIL driver doesn't honor this
requirement. Hence, generate a mapping on the physical address
and use that to collect the minidumps.

Requests sent to RPMH can be sent as fire-n-forget or response required,
with the latter ensuring the command has been completed by the hardware
accelerator. Commands in a request with tcs_cmd::wait set, would ensure
that those select commands are sent as response required, even though
the actual TCS request may be fire-n-forget.
Also, commands with .wait flag were also guaranteed to be complete
before the following command in the TCS is sent. This means that the
next command of the same request blocked until the current request is
completed. This could mean waiting for a voltage to settle or series of
NOCs be configured before the next command is sent. But drivers using
this feature have never cared about the serialization aspect. By not
enforcing the serialization we can allow the hardware to run in parallel
improving the performance.
Let's clarify the usage of this member in the tcs_cmd structure to mean
only completion and not serialization. This should also improve the
performance of bus requests where changes could happen in parallel.
Also, CPU resume from deep idle may see benefits from certain wake
requests.
