Ohad Sharabi 5d6a198f9d habanalabs: reset device in case of sync error
As the F/wW is the first to detect out of sync event, a new event is
added to notify the driver on such event. In which case the driver
performs hard reset.

Alon Mizrahi 4147864e8d habanalabs: fetch pll frequency from firmware
Once firmware security is enabled, driver must fetch pll frequencies
through the firmware message interface instead of reading the registers
directly.

Ofir Bitton 763a0b4d81 habanalabs: Fix alignment issue in cpucp_info structure
Because the device CPU compiler aligns structures to 8 bytes,
struct cpucp_info has an alignment issue as some parts
in the structure are not aligned to 8 bytes.
It is preferred that we explicitly insert placeholders inside
the structure to avoid confusion

in order to validate this scenario, we printed both pointers:

__u8 cpucp_version[VERSION_MAX_LEN]; (0xffff899c67ed4cbc)
__le64 dram_size;                    (0xffff899c67ed4d40)

we see difference of 132 bytes although the first array
is only 128 bytes long, Meaning compiler added a 4 byte padding.

Oded Gabbay 2f55342c5e habanalabs: replace armcp with the generic cpucp
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.
