arm: omap2+: add missing HWMOD_NO_IDLEST in 81xx hwmod data

Add missing HWMOD_NO_IDLEST hwmod flag for entries not
having omap4 clkctrl values.
The emac0 hwmod flag fixes the davinci_emac driver probe
since the return of pm_resume() call is now checked.

This solves the following boot errors :
[    0.121429] omap_hwmod: l4_ls: _wait_target_ready failed: -16
[    0.121441] omap_hwmod: l4_ls: cannot be enabled for reset (3)
[    0.124342] omap_hwmod: l4_hs: _wait_target_ready failed: -16
[    0.124352] omap_hwmod: l4_hs: cannot be enabled for reset (3)
[    1.967228] omap_hwmod: emac0: _wait_target_ready failed: -16
