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