omap3: pm: Update Triton2 scripts

Updated the sleep, wakeup & warm_reset sequence as recommended by David 
Derrick.
Used broadcast command, modified the resource type association and remap 
sleep_state.
Added the new script changes for zoom[2,3] boards.

VDD1, VDD2 and VPLL1 are remapped to turn off during sleep state.
Changed RES_TYPE2 of VPLL1, VDD1, VDD2, REGEN, NRESPWRON & SYSEN to '1'
and VINTANA1, VINTANA2, VINTDIG, VIO, CLKEN & HFCLKOUT to '2'.
How about VMMC,VAUX and other resources?

These LDOs are controlled by drivers using regulator frame work, not through 
TRITON power sequence.


HFCLKOUT is attached to P3, to disable HFCLK when clk_req signal is 
toggled.
