To lpc32xx_adc driver, when platform_get_resource or

On i.MX6/7, now the bootflow is U-Boot->OP-TEE->Linux, OP-TEE will

Tested on i.MX7D-SDB with/without OP-TEE OS.
The privileged dev id range is [TEE_NUM_DEVICES / 2, TEE_NUM_DEVICES).
The non-privileged dev id range is [0, TEE_NUM_DEVICES / 2).
So when finding a slot for them, need to use different max value.

Hi Jens, Ulf
We met an issue is OP-TEE is actively doing some DMA operations, such as CAAM
DMA, while Linux is doing some ddr freq change and will let ddr into
self-refresh state, this will cause issues.
On ARMv8 i.MX, we have code request_bus_freq/release_bus_freq to ask ATF to
make ddr into/
In gic_iterate_rdists, ret will never be 0 when `ret ? -ENODEV : 0` at
the end of function, so let's directly return -ENODEV.

It does not make sense to only get value from pll->base and assign

Follow other i.MX6/7 machince code to check return value
of imx_soc_device_init and warn when fail.
Also drop of_platform_default_populate, because
"arch_initcall_sync(of_platform_default_populate_init);" could be
used to populate the device tree.

When imx_data->pinctrl is not a valid pointer, pinctrl_lookup_state
will trigger kernel panic.
When we boot Dual OS on Jailhouse hypervisor, we let the 1st Linux to

settings.
