dmaengine: Remove dependency on MACH_BCM2708

Commit 96286b576690 ("dmaengine: Add support for BCM2835") added an
optional dependency on MACH_BCM2708. But there's no Kconfig symbol
MACH_BCM2708.

(There was an entry for MACH_BCM2708 in arch/arm/tools/mach-types from
v2.6.37 until v3.2. But it seems that entry was never used in the tree.)

This optional dependency can safely be removed.

acpi-dma: use devm_release() instead of devm_destroy()

Since devm_destroy() doesn't call release function we have to use
devm_release() instead.

acpi-dma: convert to return error code when asked for channel

Currently acpi_dma_request_slave_chan_by_index() and
acpi_dma_request_slave_chan_by_name() return only requested channel or NULL.
This patch converts them to return appropriate error code instead of NULL in
case of unsuccessfull request.

ledtrig-cpu: Handle CPU hot(un)plugging

When CPU is hot(un)plugged, no syscore notification is being
generated, nor is cpuidle involved. This leaves the CPU LED
turned on, because the dying thread is doing some work (LED on)
and than it is... well, dying (LED still on :-)

Added notifier block for hot(un)plugging operations, generating
existing trigger events.

leds: Turn off led if blinking is disabled

When using the timer trigger and setting delay_on to 0, the led
will stay in whatever state is was in, while intuitively one
would expect it to turn off. This patch changes the behaviour to
turn it off.
