This reverts the arch/arm/mach-imx/imx_bootaux.c changes of commit
805b3cac1e. The loader function name was changed so that it does
not clash with the generically available function in lib/elf.c.
imx-bootaux loads an elf file linked for an auxilary core. Thus the
loader function requires address translation from the auxilary core's
address space to where those are mapped into U-Boot's address space.
So the elf loader is specific and must not be replaced with a generic
loader which doesn't provide the address translation functionality.
Fixes commit 805b3cac1e ("lib: elf: Move the generic elf
loading/validating functions to lib")

Some board like imx8mm-evkb, IO voltage switch from 3.3v to 1.8v need
around 18ms, common code only delay 10ms, so need to delay extra 8ms.
Otherwise voltage switch will timeout when wait for data0 line.
This IO voltage switch time depends on board design, depend on the
PMIC and capacitance. imx8mm-evkb board use PCA9450(PMIC) and 10uF
capacitance.

1. The hab_rvt base and function vectors are different as i.MX6/7
2. Need to bypass an workaround for i.MX6 to fix problem in MMU.
3. The x18 register needed save & restore before calling any HAB API. According
to ARM procedure call spec, the x18 is caller saved when it is used as
temporary register. So calling HAB API may scratch this register, and
cause crash once accessing the gd pointer.
On ARMv7, the r9 is callee saved when it is used as variable register. So
no need to save & restore it.
4. Add SEC_CONFIG fuse for iMX8M
When current EL is not EL3, the direct calling to HAB will fail because
CAAM/SNVS can't initialize at non-secure mode. In this case, we use
SIP call to run the HAB in ATF.
