Commit 68523f4233de5f233478dde0a63047b4efb710b8 (ARM: OMAP4:
Workaround the OCP synchronisation issue with 32K synctimer)
does not include GP Timers in ABE domain. Since synchronization
issue is applicable to all GPTIMER[1-12], we also need to set
static dependency of MPUSS with abe_clkdm and l4_per_clkdm.
Dependency with l4_per_clkdm timers is already set in commit
12f27826bdaf56b01cbdfc8bdeb577ebc106dee3 (ARM: OMAP4: PM: Keep
static dep between MPUSS-EMIF and MPUSS-L3/L4 and DUCATI-L3).
Therefore, set static dependency of MPUSS with abe_clkdm.
