According to the AT24 EEPROM bindings the compatible string should
contain first the actual manufacturer, and second the corresponding
atmel model.
Add the atmel compatible fallback accordingly.

The simple-audio-card's microphone widget currently connects to the
headphone jack. Routing the microphone input to the microphone jack
allows for independent operation of the microphone and headphones.
This resolves the following boot-time kernel log message, which
indicated a conflict when the microphone and headphone functions were
not separated:
debugfs: File 'Headphone Jack' in directory 'dapm' already present!

This reverts commit 3935fbc87d.
CTRL_SLEEP_MOCI# is a signal that is defined for all the SoM
implementing the Verdin family specification, this signal is supposed to
control the power enable in the carrier board when the system is in deep
sleep mode. However this is not possible with Texas Instruments AM62
SoC, IOs output buffer is disabled in deep sleep and IOs are in
tri-state mode.
Given that we cannot properly control this pin, force it to be always
high to minimize potential issues.

Previously, we had the sleep-moci pin set to always on. However, the
Dahlia carrier board supports disabling the sleep-moci when the system
is suspended to power down peripherals that support it. This reduces
overall power consumption. This commit adds support for this feature by
disabling the reg_force_sleep_moci regulator and adding a new regulator
for the USB hub that can be turned off when the system is suspended.

Add a GPIO hog to release PCIe reset on the carrier board, this is
required to use M.2 or mPCIe cards.
Verdin AM62 does not have any PCIe interface, however the Verdin family
has PCIe and normally an M.2 or mPCIe slot is available in the carrier
board that can be used with cards that use only the USB interface toward
the host CPU, for example cellular network modem.

In current configuration, wm8904 codec on Dahlia carrier board provides
distorted audio output. This happens due to reference clock is fixed to
25MHz and no FLL is enabled. During playback following parameters are set:
44100Hz:
[ 310.276924] wm8904 1-001a: Target BCLK is 1411200Hz
[ 310.276990] wm8904 1-001a: Using 25000000Hz MCLK
[ 310.277001] wm8904 1-001a: CLK_SYS is 12500000Hz
[ 310.277018] wm8904 1-001a: Selected CLK_SYS_RATIO of 256
[ 310.277026] wm8904 1-001a: Selected SAMPLE_RATE of 44100Hz
[ 310.277034] wm8904 1-001a: Selected BCLK_DIV of 80 for 1562500Hz BCLK
[ 310.277044] wm8904 1-001a: LRCLK_RATE is 35
Deviation = 1411200 vs 1562500 = 10.721%
Also, LRCLK_RATE is 35, should be 32.
48000Hz:
[ 302.449970] wm8904 1-001a: Target BCLK is 1536000Hz
[ 302.450037] wm8904 1-001a: Using 25000000Hz MCLK
[ 302.450049] wm8904 1-001a: CLK_SYS is 12500000Hz

Enabling wm8904 FLL via providing mclk-fs property to simple-audio-card
configures clocks properly, but also adjusts audio reference clock
(mclk), which in case of TI AM62 should be avoided, as it only
supports 25MHz output [1][2].
This change enables FLL on wm8904 by providing mclk-fs, and drops
audio reference clock out of DAI configuration, which prevents
simple-audio-card to adjust it before every playback [3].
