Fix types of arch.h definitions

Define the values as unsigned int or unsigned long long based on the
actual size of the register. This prevents subtle issues caused by
having a type that is too small. For example:

#define OPTION_ENABLE 0x3
#define OPTION_SHIFT 32

uint64_t mask = OPTION_ENABLE << OPTION_SHIFT;

Because OPTION_ENABLE fits in an int, the value is considered an int.
This means that, after shifting it 32 places to the left, the final
result is 0. The correct way to define the values is:

#define OPTION_ENABLE ULL(0x3)
#define OPTION_SHIFT U(32)

In this case, the compiler is forced to use a 64 bit value from the
start, so shifting it 32 places to the left results in the expected
value.

Tegra: Fix up INFO() message

With commit cf24229e6ef4 ("Run compiler on debug macros for type
checking"), the compiler will now always evaluate INFO() macro
calls, no matter the LOG_LEVEL value. Therefore, any variable
referenced in the macro has to be be defined.

Address this issue by removing the local variable and using the
expression it was assigned directly in the INFO() call.
