Rather than use a governor to keep these domains always-on, instead
use the flag GENPD_FLAG_ALWAYS_ON. This has the same effect, but with
much lower overhead since the governor path is not used at all.

In Versal all reset indices includes Class, SubClass, Type, Index

Underlying firmware in Versal have such classification and expects
the ID to be this way.

Use DEFINE_SHOW_ATTRIBUTE macro to simplify the code.
Along with this change, we get additionally:
.owner = THIS_MODULE,
.llseek = seq_lseek,
1. The llseek method is used to change the current read/write position
in a file which can be ignored if you don't use it.
2. The owner is not even a method. Instead, it is a pointer to the
module that “owns” this structure; it is used by the kernel to maintain
the module's usage count which can be ignored.

Enable support for the BPMP on Tegra234 to avoid relying on Tegra194
being enabled to pull in the needed OF device ID table entry.
On simulation platforms the BPMP hasn't booted up yet by the time we
probe the BPMP driver and the BPMP hasn't had a chance to mark the
doorbell as ringable by the CCPLEX. This corresponding check in the
BPMP driver will therefore fail. Work around this by disabling the
check on simulation platforms.

This function extracts the PRE_SI_PLATFORM field from the HIDREV

(silicon, simulation, ...). Note that while only Tegra194 and later
define this field, it should be safe to call this on prior generations
as well since this field should read as 0, indicating silicon.

In preparation to enable building SCMI as a single module, let us move
the SCMI protocol registration call into the driver. This enables us
to also add unregistration of the SCMI protocols.
The main reason for this is to keep it simple instead of maintaining
it as separate modules and dealing with all possible initcall races
and deferred probe handling. We can move it as separate modules if
needed in future.
