a7caa8da79 gpu: nvgpu: fix misra dir 4.6 and rule 20.7 
Fix below misra violations:

directive_4_6_violation: Using basic numerical type "int" rather than
                         a typedef that includes size and signedness
                         information.
rule_20_7_violation: Macro parameter expands into an expression without
                     being wrapped by parentheses

1f2f414fde gpu: nvgpu: fix misra 8.13 violation 
MISRA Advisory Rule 8.13 states that a pointer should point to a
const-qualified type wherever possible.

This change eliminates such violations from the use of
nvgpu_timeout_expired_msg_cpu() by marking the temporary
struct nvgpu_timeout pointer const.

ddaf1daae4 gpu: nvgpu: modify nvgpu_timeout_expired for UT 
In the current logic for nvgpu_timeout_expired(), function always
returns 0 if fault injection is enabled. This only helps for testing
timeout not expired scenarios. However, if nvgpu_timeout_expired() is
used in a while(true) loop, it is impossible to break the infinite loop.
This patch modifies nvgpu_timeout_expired() to not expire until fault
injection counter is non-zero. The function will now return -ETIMEDOUT
when fault injection is enabled and counter is zero.

e668442e92 gpu: nvgpu: modify nvgpu_timeout_expired() for UT 
Currently, nvgpu_timeout_expired returns -ETIMEDOUT almost always.
Modifying the macro provides more control on return value, and we can
return 0 indicating timeout not expired. This will allow timeout not
expired branch cbranch coverage.
