This reduces the needed modifications to the mainline Linux kernel and
also makes the regmap package work with an out of tree kernel which
does not have these modifications.
The regmap-core is only added when it is really build as a module.
The regmap-core is normally bool so it cannot be built as a module in an
unmodified kernel. When it is selected by on other kernel module it will
always be selected as build in and it also does not show up in
$(LINUX_DIR)/modules.builtin as it is not supposed to be a kernel module.
When it is not in $(LINUX_DIR)/modules.builtin the build system expects
it to be built as a .ko file.
Just check if the module is really there and only add it in that case.
This splits the regmap package into multiple packages, one for each bus type.
This way only the bus maps which are really needed have to be added.
This also splits the I2C, SPI and MMIO regmap into separate packages to not
require all these subsystems to build them, on an unmodified upstream kernel
this also causes problems in some situations.

FS#256
Fix audio not working due to unset SND_PCM_TIMER. CONFIG_SND_PCM_TIMER
is required for ALSA to work (at least for some audio devices),
otherwise applications using sound may fail. Can be reproduced by
installing "alsa-utils-tests" and running "speaker-test":
...
ALSA lib pcm_direct.c:1159:(snd1_pcm_direct_initialize_poll_fd) unable to open timer 'hw:CLASS=3,SCLASS=0,CARD=0,DEV=0,SUBDEV=0'
ALSA lib pcm_dmix.c:1106:(snd_pcm_dmix_open) unable to initialize poll_fd
Playback open error: -19,No such device
The kernel size does not increase, only the size of the kernel module
increases.

The kmod-sound-hda-core module attempts to package snd-hda-core.ko which
does not exist in Linux 3.18, therfore only use it for kernels >= 4.1

Prior to kernel 4.4, the hda-intel module depends on the hda-controller
utility submodule so bundle it for the older kernel versions.

This patch set adds support for PCI Intel HD Audio
sound devices. This is useful for multimedia packages
in the packages feed that one may use to create audio
servers.

Useful when using sound players that can send to icecast, etc. without any sound device attached.

The kernel Kconfig dependency lists X86, and we will fail building this module
on other platforms such as Malta.
