soc/intel/alderlake: Rework the GPIO PAD Pin numbers
This patch creates a `relative increment by 1` macro to let SoC
gpio pad configuration to be more flexible while adding support
for newer PCH SoC.
With this changes adding GPIO controller support for PCH-N would
become really simple without too much of code duplication.
For example: ADL-N has added `GPP_I` pins into community 1 hence,
the additional code for `PCH-N` whould appear incremetal to ADL-P.
> #define GPP_B 0x0
> #define GPP_T INC(GPP_B)
> #define GPP_A INC(GPP_T)
> #define GPP_R INC(GPP_A)
> #define GPD INC(GPP_R)
> #define GPP_S INC(GPD)
> if CONFIG(SOC_INTEL_ALDERLAKE_PCH_N)
> #define GPP_I INC(GPP_S)
> #define GPP_H INC(GPP_I)
> #else
> #define GPP_H INC(GPP_S)
> #endif
> #define GPP_D INC(GPP_H)
