Currently the user cannot interpret the PLL information based on index
as its exposed as an integer.
This commit exposes ASIC specific PLL indexes and maps it to a generic
FW compatible index.

As F/ security indication must be available before driver approaches
PCI bus, F/W security should be derived from PCI id rather than be
fetched during boot handshake with F/W.

In order to use minimum of hard coded values common to LKD and F/W
a dynamic method to work with PLLs is introduced in this patch.
Formerly asic specific PLL numbering is now common for all asics.
To be backward compatible a bit in dev status is defined, if the bit is
not set LKD will keep working with old PLL numbering.

F/W message returns 64bit value but up until now we casted it to
a 32bit variable, instead of receiving 64bit in the first place.

The new state indicates that device should be reset in order
to re-gain funcionality.
This unique state can occur if reset_on_lockup is disabled
and an actual lockup has occurred.

ArmCP mandates that the device CPU is always an ARM processor, which might
be wrong in the future.
Most of this change is an internal renaming of variables, functions and
defines but there are two entries in sysfs which have armcp in their
names. Add identical cpucp entries but don't remove yet the armcp entries.
Those will be deprecated next year. Add the documentation about it in sysfs
documentation.

In Gaudi, the default max power setting is different between PCI and PMC
cards. Therefore, the driver need to set the default after knowing what is
the card type.
The current code has a bug where it limits the maximum power of the PMC
card to 200W after a reset occurs.
