ARM: tegra: Fix save_boot_params() prototype

Browse source 
The save_boot_params() function takes as its first four arguments the
first four registers. On 32-bit ARM these are r0, r1, r2 and r3, all of
which are 32 bits wide. However, on 64-bit ARM thene registers are x0,
x1, x2 and x3, all of which are 64 bits wide. In order to allow reusing
the save_boot_params() implementation on 64-bit ARM, change it to take
unsigned long parameters rather than the fixed size 32-bit integers.
This ensures that the correct values are passed.
