OMAP4: HWMOD: UART1: disable smart-idle.

OMAP4: HWMOD: UART1: disable smart-idle.

UART module gets stuck in transition when smart-idle enabled.
By enabling HWMOD_SWSUP_SIDLE flag in UART1 HWMOD, ensures that
module's smart-idle feature is disabled and it is put to
forced-idle and no-idle during pm-runtime.

Seen similar issue with UART3 and was fixed by enabling
HWMOD_SWSUP_SIDLE flag in uart3 HWMOD.

OMAP4: DSS: Implement workaround for Errata ID:i733.

Description of Errata i733:
Due to wrong timings, all register accesses transitioning through the L4
interconnect toward DSS are not reliable.

Workaround:
DSS register access should be addressed through the L3 interconnect.

This change fixes errata by using L3 for access to DSS in dss_hwmod
instead of L4.
