qcacmn: Process the negative AFC standard EIRP power values

When we receive a negative EIRP value from AFC APP with UINT, we treat it
as a positive value. See the following reasons why EIRP power value
was changed when we received it as a UINT.

1. In the reg_find_eirp_in_afc_eirp_obj function, the afc 'eirp_power'
(16-bit) value is in units of 0.01, and it is an unsigned integer. For
example, if the negative value is "-1400" then it becomes "64136". With
this value, when we try to get the original EIRP value using division
(eirp_obj->eirp_power / EIRP_PWR_SCALE(100)), it returns "641", but the
expected EIRP value is -14.

2. In the reg_get_sp_eirp function, both the variables 'afc_eirp_pwr'
(8-bit) and 'reg_sp_eirp_pwr'(16-bit) are declared as unsigned integers.
For example, when "-14," is assigned to "afc_eirp_pwr", it becomes "242".
And assuming 'reg_sp_eirp_pwr' is "36", the minimum of the two variables,
using QDF_MIN(afc_eirp_pwr, reg_sp_eirp_pwr), becomes "36", but the
expected minimum is "-14 or 242".

Process the positive or negative EIRP values that are received from AFC
application. Receive it as an int instead of an unint and typecast it to
int when we check for minimum value from afc power and standard power.
