Add a module to configure the tamper and secure violation of
the SNVS using the SCU API.
The module also adds some commands:
- snvs_cfg: Configure the SNVS HP and LP registers
- snvs_dgo_cfg: Configure the SNVS DGO bloc if present (8QXP)
- tamper_pin_cfg: Change the configuration of the tamper pins
- snvs_clear_status: Allow to write to LPSR and LPTDSR to clear
status bits

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.

Add sc_pm_is_partition_started to check whether a partition
has been started. This will be used to detect M4 partition booted up or
not, then we could choose which dtb to use. If M4 is up, we need
use dtb, such as imx8qm-mek-rpmsg.dtb.

When boot_dev is true, fill boot device. However the original logic is when
boot_dev is false, fill boot device, this will trigger data abort.
Also fix sc_misc_get_control when using pointer val.

Add clk/misc/pad/pm/rm scfw api implementaion for different
drivers to invoke. The low level code is using misc_call
to invoke imx8_scu driver.
