Set CLK01 and CLK02 to 24MHz and enable it in CCM_CCOSR register.
This clock is used by both the audio codec (CLKO1) and by the CSI camera
(CLKO2) and is expected to be 24MHz.
Despite the wrong 16.5MHz there was no real issue because of the wrong
frequency since Linux reconfigures the clocks afterward, however this
was triggering an issue with noise coming from the SGTL5000 audio codec.
The problem is that the SGTL5000 does not have a reset pin and after it
is configured if the input MCLK clock is disabled it produces a constant
noise on its output, this was happening on software reboot.
Forcing the clock to be enabled in U-Boot prevent the problem by making
sure that the clock is always available, without this change as soon as
Linux was changing the clock tree (setting clk_out_sel=1 without setting
clko2_en=1) the noise would start till the actual clock was enabled
(clko2_en=1) during the SGTL5000 driver probe.

NXP used to setup the gpmi clock root from gpmi_clk in early versions
in their downstream BSP. [1]
However on mainline the gpmi clock root was always setup from enfc
since the beginning of the i.MX 6 series SoCs, which is still the same
today. [2]
NXP followed the mainline approach at some point and changed
setup_gpmi_io_clk to setup gpmi clock root from enfc which left faulty
code behind in our board file. [3]
This commit follows the change of NXP as it improves the performance of
the NAND from ~1.2 MiB/s to ~12 MiB/s. [3]
This change was verified to work in recovery-mode and u-boot loaded
from NAND on all four Colibri iMX6ULL SKUs from Toradex.
The frequency used to read the NAND, measured on RE# (Read Enable):
before this patch: 1.4 MHz
after this patch: 22 MHz
in Linux Kernel: 50 MHz

support but never supported a kernel so old as to require it. Further,
some platforms are old enough to support both, but are well supported by
devicetree booting, and have been for a number of years. This is
because some of the ATAGs related functions have been re-used to provide
the same kind of information, but for devicetree or just generally to
inform the user. When needed still, rename these functions to
get_board_revision() instead, to avoid conflicts. In other cases, these

Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to. This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value. Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.
Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g. COLD vs WARM resets). As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).
To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely. Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.
This transformation was done with the following coccinelle patch:
