The Kobo Aura is an e-book reader released in 2013.

With the devicetree in its current state, the kernel will boot and run
for about ten seconds. To solve this, the embedded controller needs to
be told that the system should stay powered on. This will be done in a
later patchset.

- The IOMUXC mode bits for the SD interfaces were taken from the
  vendor's U-Boot fork.
- The bus width of the eMMC is 4 bits in the vendor kernel, but I
  achieved better performance with 8 bits.
- The SDIO clock frequency for the WiFi chip is 25MHz in the vendor
  kernel, but the WiFi chip (BCM43362) supports 50MHz, which works
  reliably on this board and gives slightly better performance.
- The I2C pins' IOMUXC settings come from the vendor's U-Boot fork.

The correct DT property for specifying a GPIO used for reset
is "reset-gpios", the driver now accepts this name, use it here.

Note the GPIO polarity in the driver was ignored before and always
assumed to be active low, when all the DTs are fixed we will start
respecting the specified polarity. Switch polarity in DT to the
currently assumed one, this way when the driver changes the
behavior will not change.

Since 25aaa75d SDMA driver uses clock rates of "ipg" and "ahb"
clock to determine if it needs to configure the IP block as operating
at 1:1 or 1:2 clock ratio (ACR bit in SDMAARM_CONFIG). Specifying both
clocks as IMX5_CLK_SDMA results in driver incorrectly thinking that
ratio is 1:1 which results in broken SDMA funtionality. Fix the code
to specify IMX5_CLK_AHB as "ahb" clock for SDMA, to avoid detecting
incorrect clock ratio.
