The variable 'mode' is declared as unsigned int in local function.
The return value of function amd_pmf_get_pprof_modes(dev) is int and
it is stored in the 'mode' variable. Also the value of 'mode' variable
is compared with 0 which is signed int by default. Thus redeclaring the
variable to signed int.

This fixes warning such as:
drivers/platform/x86/amd/pmf/sps.c:128:5-9:
WARNING: Unsigned expression compared with zero: mode < 0
