This macro is not used anymove in atmel-mci driver. It has been removed
by a patch that was dealing with dw_dmac.c e2b35f3:

29a0e7beab ARM: tegra: retain L2 content over CPU suspend/resume
The L2 RAM is in different power domain from the CPU cluster. So the
L2 content can be retained over CPU suspend/resume. To do that, we
need to disable L2 after the MMU is disabled, and enable L2 before
the MMU is enabled. But the L2 controller is in the same power domain
with the CPU cluster. We need to restore it's settings and re-enable
it after the power be resumed.

d552920a02 ARM: tegra30: cpuidle: add powered-down state for CPU0
This is a power gating idle mode. It support power gating vdd_cpu rail
after all cpu cores in "powered-down" status. For Tegra30, the CPU0 can
enter this state only when all secondary CPU is offline. We need to take
care and make sure whole secondary CPUs were offline and checking the
CPU power gate status. After that, the CPU0 can go into "powered-down"
state safely. Then shut off the CPU rail.

Be aware of that, you may see the legacy power state "LP2" in the code
which is exactly the same meaning of "CPU power down".

cf63346401 ARM: dt: tegra: ventana: define pinmux for ddc
Tegra 2's I2C2 controller can be routed to either the PTA
or DDC pin group on Ventana. So:
- Remove the HDMI function definition of pta pingroup
- Define child i2c adapters(ddc & pta) for I2C2 controller
