ARM: OMAP: DTS: N900: fix onenand timings

Commit a758f50f10cf ("mtd: onenand: omap2: Configure driver from DT")
started using DT specified timings for GPMC, and as a result the
OneNAND stopped working on N900 as we had wrong values in the DT.
Fix by updating the values to bootloader timings that have been tested
to be working on Nokia N900 with OneNAND manufacturers: Samsung,
Numonyx.

regulator: twl: Constify regulator_ops

These regulator_ops variables never need to be modified, make them const so
compiler can put them to .rodata.

regulator: twl: voltage lists for vdd1/2 on twl4030

_opp_supported_by_regulators() wrongly ignored errors from
regulator_is_supported_voltage(), so it considered errors as
success. Since
commit 498209445124 ("regulator: core: simplify return value on suported_voltage")
regulator_is_supported_voltage() returns a real boolean, so
errors make _opp_supported_by_regulators() return false.

That reveals a problem with the declaration of the VDD1/2
regulators on twl4030.
The VDD1/VDD2 regulators on twl4030 are neither defined with
voltage lists nor with the continuous flag set, so
regulator_is_supported_voltage() returns false and an error
before above mentioned commit (which was considered success)
The result is that after the above mentioned commit cpufreq
does not work properly e.g. dm3730.

[    2.490997] core: _opp_supported_by_regulators: OPP minuV: 1012500 maxuV: 1012500, not supported by regulator

[    2.537750] cpu cpu0: _opp_add: OPP not supported by regulators (800000000)

The patch fixes declaration of VDD1/2 regulators by
adding proper voltage lists.

ARM: n900_defconfig: compile RTC driver in kernel

This prevents wrong timestamps on early kernel boot
time and removes the need to have a service/udev rule

debian: preserve /debian/ on 'make clean'

debian: remove /debian/ from .gitignore

debian: fill /debian/ directory with content

debian: use linux native scripts for packaging

Packages added:
 - linux-image-n900-dbg
 - linux-headers-n900

This should allow to build kernel modules out of tree.

Update debian/changelog (5.0.5-1)

debian: fix linux-headers-n900 when crossbuilding

Build kernel related binaries in target architecture format after cross
building. This allows to run DKMS on target device successfully.

debian: add gbp.conf needed by jenkins-debian-glue

debian: update README for default config management

debian: rules: fix warning: 'build-arch' is missing

debian/README: add instructions for cross building

debian/rules: replace variables with proper names

See dpkg-architecture(1) and
https://wiki.debian.org/CrossBuildPackagingGuidelines

debian: change source format to '3.0 (native)'

We don't use quilt patches. Having '3.0 (quilt)' can confuse users and
build system when additional patches/configuration changes are applied
to the same kernel version.
