ARM: OMAP3: clock: Back-propagate rate change from cam_mclk to dpll4_m5

The cam_mclk clock is generated through the following clocks chain:

dpll4 -> dpll4_m5 -> dpll4_m5x2 -> cam_mclk

As dpll4_m5 and dpll4_m5x2 do not driver any clock other than cam_mclk,
back-propagate the cam_clk rate changes up to dpll4_m5.

omap3isp: Set cam_mclk rate directly

Now that the cam_mclk rate changes are back-propagated to dpll4_m5_ck we
can set the cam_mclk rate directly instead of manually setting the rate
of the parent clock.

drm/nouveau: use different register to wait for secret scrubber

Fixes long delay when waiting for scrubber on some secret engines.
The exit interrupt seems to not always be generated, so use secret
scrubber active register instead.

Later fuc engines also no longer generate an interrupt, so don't wait
there.

ARM: OMAP AM33XX: clock data: SET_RATE_PARENT in lcd path

LCDC clock node is a one that does not have set rate capability. It
just passes on the rate that is sent downstream by it's parent. While
lcdc clock parent and it's grand parent - dpll_disp_m2_ck and
dpll_disp_ck has the capability to configure rate.

And the default rates provided by LCDC clock's ancestors are not
sufficient to obtain pixel clock for current LCDC use cases, hence
currently display would not work on AM335x SoC's (with driver
modifications in platfrom independent way).

Hence inform clock framework to propogate set rate for LCDC clock as
well as it's parent - dpll_disp_m2_ck. With this change, set rate on
LCDC clock would get propogated till dpll_disp_ck via dpll_disp_m2_ck,
hence allowing the driver (same driver is used in DaVinci too) to set
rates using LCDC clock without worrying about platform dependent clock
details.

ARM: OMAP2+: Get rid of custom OMAP_32K_TIMER_HZ

The timekeeping doesn't depend on HZ value in presence of fine grained
clocksource and hence there should not be any time drift because of HZ
value which was chosen to be divisor of 32768.

OMAP has been using HZ = 128 value to avoid any time drift issues
because of 32768 HZ clock. But with various measurements performed
with HZ = 100, no time drift is observed and it also proves the
point about HZ not having impact on time keeping on OMAP.

ARM: at91/DT: remove atmel,use-dma-* from 9x5 and 9n12 USART nodes

Fix the use of USART on both at91sam9x5 and at91sam9n12. In DTS, the
atmel,use-dma-[rx|tx] property is present but a DMA channel cannot be used.
Indeed the connexion between the DMA engine and the slave is not implemented
yet in Device Tree.
Note however that this property is also used for PDC (private DMA) on older
SoCs. This is why the driver alone cannot determine the validity of this
property.
