On gs101 SoC the fltcon0 (filter configuration 0) offset isn't at a fixed offset like previous SoCs as the fltcon1 register only exists when there are more than 4 pins in the bank.
Add a eint_fltcon_offset and new GS101_PIN_BANK_EINT* macros that take an additional fltcon_offs variable.
This can then be used in suspend/resume callbacks to save and restore the fltcon0 and fltcon1 registers.
