The MCE driver's helper functions were using postive values as error
codes.

This patch updates the functions to return negative values as error
codes instead. Some functions are updated to use the right error code.

This patch updates the header, t194_nvg.h, to v6.4. This
gets it in synch with MTS pre-release 2 - cl39748439.

"Strict checking" is a mode where secure world can access
secure-only areas unlike legacy mode where secure world could
access non-secure spaces as well. Secure-only areas are defined
as the TZ-DRAM carveout and any GSC with the CPU_SECURE bit set.
This mode not only helps prevent issues with IO-Coherency but aids
with security as well.

This patch implements the programming sequence required to enable
strict checking mode for Tegra194 SoCs.

The MCE driver checks the NVG interface version during boot and
disaplys the hardware and software versions on the console. The
software version is being displayed as zero.

This patch updates the prints to use the real NVG header version
instead.

This patch does the following:
- cstate_info variable is used to pass on requested cstate to mce
- Currently, cg_cstate is encoded using 2 bits(bits 8, 9) in cstate_info
- cg_cstate values can range from 0 to 7, with 7 representing cg7
- Thus, cg_cstate is to be encoded using 3 bits (val: 0-7)
- Fix this, as per ISS and ensure bits 8, 9, 10 are used

This patch cleans up the mce driver files to remove all the unsupported
functionality. The MCE/NVG interface is not restricted to the EL3 space,
so clients can issue commands to the MCE firmware directly.

Main fixes:

Added explicit casts (e.g. 0U) to integers in order for them to be
  compatible with whatever operation they're used in [Rule 10.1]

Fix variable essential type doesn't match [Rule 10.3]

Added curly braces ({}) around if/while statements in order to
  make them compound [Rule 15.6]

Voided non c-library functions whose return types are not used
  [Rule 17.7]
