The phy is necessary for the dwc2 controllers driving the usb ports
on all arm32 Rockchip socs. Both the dwc2 as well as usb downstream
drivers (mass-storage as well as usb networking) are already built-in,
so only the phy is missing to allow booting from usb-devices without
to much hassle.

We only need to have MFD_CPCAP and CPCAP_REGULATOR as built-in to
be able to mount root on the eMMC. And then POWER_RESET_GPIO
is good to have built-in. The rest of the devices can be loadable
modules.

This gets various devices such as regulators, touchscreen, power
button, HDMI audio, LEDs, RTC, and ADC working.

Note that omapdrm needs to be configured manually as we're still
using omapfb by default.

The imx6sl-evk board has a LAN8720A ethernet phy supported by SMSC_PHY.
Add this driver to the default imx config since the device is present on
one of the evaluation boards.

This used to work mostly fine with the generic phy driver until
commit 0878fff1 ("net: phy: Do not perform software reset for
Generic PHY"). The fact that soft reset is no longer performed
apparently causes RX to sometimes failes which can cause netboot to
timeout on DHCP. This is eventually retried and it works after link
up/down but can takes 90 seconds to reach the login prompt.

This was generated with "make savedefconfig" and it includes a few
additional minor cleanups.

IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively.  However there are still
some users (mostly old or/and embedded non-x86 systems) that
have not converted from using IDE subsystem to libata PATA
drivers.  This doesn't seem to be good thing in the long-term
for Linux as while there is less and less PATA systems left
in use:

* testing efforts are divided between two subsystems

* having duplicate drivers for same hardware confuses users

This patch converts davinci_all_defconfig to use libata PATA
drivers.

Current CMA size of 64 Mbytes is right on the edge of being small when
several drivers need to allocate large CMA buffers.

For example, if the s5p-mfc driver needs to pre-allocate CMA memory to
decode a H.264 1080p video, then there won't be enough CMA memory left
for other drivers, such as the exynos-drm driver that may need to
allocate GEM buffers for the display manager.

Increasing CMA size to 96 Mbytes in exynos_defconfig addresses use-cases
such as these.
