- Fix the data type violations based on MISRA-C requirements
- Add '-fsigned-char' in Makefile to let the compiler treats 'char' be
signed, like 'signed char'.
Otherwise, the static checker treats 'char', 'signed char' and 'unsigned
char' as three different types.
- Fix some minor coding style issues, such as TAB issues, line over 80
characters issues and comments style

To reduce type conversion in HV:
Update return type of function ffs64 and ffz64 as uint16;
For ffs64, when the input is zero, INVALID_BIT_INDEX is returned;
Update temporary variable type and return value check of caller
when it call ffs64 or ffz64;
Note: In the allocate_mem, there is no return value checking for
calling ffz64, this will be updated latter.
V1-->V2:
INVALID_BIT_INDEX instead of INVALID_NUMBER
Coding style fixing;
INVALID_CPU_ID instead of INVALID_PCPU_ID or INVALID_VCPU_ID;
"%hu" is used to print vcpu id (uint16_t);
Add "U/UL" for constant value as needed.
V2-->V3:
ffs64 return INVALID_BIT_INDEX directly when
the input value is zero;
Remove excess "%hu" updates.
V3-->V4:
Clean up the comments of ffs64;
Add "U" for constant value as needed.

This patch drops "#include <bsp_cfg.h>" and include the generated config.h in
CFLAGS for the configuration data.
Also make sure that all configuration data have the 'CONFIG_' prefix.
v4 -> v5:
* No changes.
v3 -> v4:
* Add '-include config.h' to hypervisor/bsp/uefi/efi/Makefile.
* Update comments mentioning bsp_cfg.h.
v2 -> v3:
* Include config.h on the command line instead of in any header or source to
avoid including config.h multiple times.
* Add config.h as an additional dependency for source compilation.
