missing the pincontrol definitions. Move PINCTRL selects to the arch

This patch adds selection of CONFIG_SPARSE_IRQ for ARCH_EXYNOS, since it
is required by multiplatform and allows to remove the legacy mach/irqs.h
header.
To make this possible, a dummy IRQ_EINT_BIT macro is added to pm-core.h
header to allow plat-samsung/pm.c compile. This macro is irrelevant for
Exynos and will be removed after reworking Samsung pm code for
multiplatform compatibility.

The powerdomain framework currently expects all powerdomains to be associated with
a corresponding voltagedomain. For some SoCs' (like the already existing AM33xx
family, or for the upcoming AM437x and DRA7 SoCs') which
do not have a Voltage controller/Voltage Processor (neither the SR I2C
bus to communicate with the PMIC) there is no need for a Powerdomain to have
a voltage domain association since there is no auto-scaling of voltages possible
using the voltage FSM.
Extend the arch operations to add an api which the powerdomain core can
then use to identify if a voltdm lookup and association for a powerdomain
is really needed.
