accel/amdxdna: Fix fatal_error_info layout in firmware interface
Adjust struct fatal_error_info to match the expected driver/firmware
interface layout.
The structure is used to retrieve debug information from firmware when
a command becomes stuck on the device. The reserved field currently
uses 128 u32 entries, which makes the structure larger than intended
and causes the layout to no longer match the firmware definition.
Reduce the reserved array size from 128 to 127 entries so the
structure matches the expected interface format.
