pinctrl: samsung: Define suspend and resume callbacks for all banks and SoCs 

Suspend and resume callbacks in Exynos/S5Pv210 pin controller drivers,
save and restore state of registers.  This operations should be done for
all banks which have external interrupts (as denoted by using
EXYNOS_PIN_BANK_EINTG/EINTW macros).

Add all banks of Exynos5260 and Exynos5420.  This is necessary step for
supporting suspend to RAM on these SoCs.
