MMU cache invalidation timeout indicates that the device is unstable and
therefore unusable.
Hence in such case do hard reset and return an error to the user if was
called from ioctl.
In addition, change the print to error level and rephrase its text.

This patch improves the security in the Debug IOCTL.
It adds checks that:
- The register index value is in the allowed range for all opcodes.
- The event types number is in the allowed range in SPMU enable.
- The events number is in the allowed range in SPMU disable.

Note that in contrary to the input structure, the user can provide an
output structure with changing size or no size at all. Therefore the user
output structure validation is already done in the Debug logic later on.

This patch changes the allocation of the host memory pages array to use
vmalloc if needed. This in order to support mapping of large memory
chunks.

This patch adds support in mapping of vmalloc memory.
In contrary to user memory, vmalloc memory is already pinned and has no
vm_area structure. Therefore a new capability was needed in order to map
this memory.
Mapping vmalloc memory is needed for Gaudi ASIC.

In contrary to user memory, kernel memory is already pinned and has no
vm_area structure. Therefore we need a new code path to map this memory.
This is a pre-requisite patch for upstreaming future ASIC support

Coresight is not supported on simulator, therefore add a boolean for
checking that (currently used by un-upstreamed code).
