defconfig: reserve ~38MB from OMAP Tiler.

We don't need 128MB reserved for Tiler1d. While video recording/playback, about ~41MB are free in the tiler and not used. This means that ~38MB are safe to keep, and should be added to the RAM.
To develop, you can check how much MBs are used in the tiler with "adb shell cat /d/tiler/map/1x1". Each line is a MB.

Revert "omap4: sdp/panda/tablet: reserve memory for dsp"

This reverts commit e699cc2c4cc3f369108d83370172138294f9840f.

DSP currently requires 4MB of memory to be set-aside to meet its
firmware requirements and can use either a fixed carveout or
a dynamically assigned carveout. The above commit uses static
carveouts for DSP in various board files. DSP does not have a
mandatory requirement to use this fixed carveout, and has been
switched over to use a dynamically allocated carveout address.
The above commit is therefore being reverted to free up unused
carveout memory.

This change simultaneously fixes a build error when the DSP
remoteproc is included in the build configuration. The build
was by the following commit:
	"OMAP4: ion: remove hardcoded carveout sizes"

TWL603X: IRQ: Migration to IRQ threaded handler

1)Removed request_irq() and replaced it with request_threaded_irq().

2)Removed generic_handle_irq() and replaced it with handle_nested_irq().
  Handling these interrupts is nested, as we are handling an interrupt
  (for e.g rtc,mmc1) when we are still servicing TWL irq.
