Rajendra Nayak 6ea74cb985 ARM: OMAP2+: hwmod: get rid of all omap_clk_get_by_name usage 
Moving to Common clk framework for OMAP would mean we no longer use
internal lookup mechanism like omap_clk_get_by_name().
get rid of all its usage mostly from hwmod and omap_device
code.

Moving to clk_get() also means the respective platforms
need the clkdev tables updated with an entry for all clocks
used by hwmod to have clock name same as the alias.

Based on original changes from Mike Turquette.

Cc: Russell King - ARM Linux <linux@arm.linux.org.uk>
[paul@pwsan.com: removed IS_ERR_OR_NULL() conversion (rmk comment);
 restricted omap_96m_alwon_fck_3630 to OMAP36xx; added missing AM35xx
 clock aliases for emac_fck, emac_ick, vpfe_ick, vpfe_fck; added
 aliases rng_ick and several emulation clocks]

/*
* This clock is a composite clock which does entire set changes then
* forces a rebalance. It keys on the MPU speed, but it really could
* be any key speed part of a set in the rate table.
*
* to really change a set, you need memory table sets which get changed
* in sram, pre-notifiers & post notifiers, changing the top set, without
* having low level display recalc's won't work... this is why dpm notifiers
* work, isr's off, walk a list of clocks already _off_ and not messing with
* the bus.
*
* This clock should have no parent. It embodies the entire upper level
* active set. A parent will mess up some of the init also.
