ARM: dts: omap4-embt2ws: Add Bluetooth

Since the required clock is now available, add bluetooth.

Note: Firmware (bts file) from device vendor reroutes tx for some time
during initialisation and later put it back, producing timeouts in
bluetooth initialisation but ignoring that command leads to proper
initialisation.

ARM: dts: omap4-embt2ws: enable 32K clock on WLAN

WLAN did only work if clock was left enabled by the original system,
so make it fully enable the needed resources itself.

ARM: dts: omap4-embt2ws: Fix pinctrl single node name warning

Looks like one pinctrl single binding warning sneaked in while we were
implementing the yaml binding. Let's fix the 'pinmux-wl12xx-gpio' does not
match any of the regexes warning by adding -pins suffix.

ARM: dts: omap: omap4-embt2ws: Let IMU driver handle Magnetometer internally

Possibility to use the i2c gate is only for compatibility reasons,
so avoid messing around with additional i2c busses.

ARM: dts: Move .dts files to vendor sub-directories

The arm dts directory has grown to 1559 boards which makes it a bit
unwieldy to maintain and use. Past attempts stalled out due to plans to
move .dts files out of the kernel tree. Doing that is no longer planned
(any time soon at least), so let's go ahead and group .dts files by
vendors. This move aligns arm with arm64 .dts file structure.

There's no change to dtbs_install as the flat structure is maintained on
install.

The naming of vendor directories is roughly in this order of preference:
- Matching original and current SoC vendor prefix/name (e.g. ti, qcom)
- Current vendor prefix/name if still actively sold (SoCs which have
been aquired) (e.g. nxp/imx)
- Existing platform name for older platforms not sold/maintained by any
company (e.g. gemini, nspire)

The whole move was scripted with the exception of MAINTAINERS and a few
makefile fixups.
