spl: atf: Fix invalid bl32 pc when bl32 is absent

'bl2_to_bl31_params->bl32_ep_info' is Null and '&bl2_to_bl31_params->bl32_ep_info->pc'
is 0x8 when bl32 is absent. That means the pc value is determined by u-boot-spl.bin.
The 0x8 offset of u-boot-spl.bin is the value of '_TEXT_BASE', i.e. CONFIG_SPL_TEXT_BASE.

So far, only rk3576 without bl32 would trigger this issue as DRAM base is 0x40000000.

Let's init bl32_{ep,image}_info even bl32 is absent.

spl: atf: add SPL_ATF_NO_PLATFORM_PARAM option

While we expect to call a pointer to a valid FDT (or NULL) as the
platform parameter to an ATF, some ATF versions are not U-Boot aware
and have an insufficiently robust (or an overzealour) parameter
validation: either way, this may cause a hard-stop with uncooperative
ATF versions.

This change adds the option to suppress passing a platform parameter
and will always pass NULL.

Debug output from ATF w/ this option disabled (i.e. default):
INFO: plat_param_from_bl2: 0x291450
Debug output from ATF w/ this option enabled:
INFO: plat_param_from_bl2: 0

spl: atf: introduce spl_invoke_atf and make bl31_entry private

This adds a new interface spl_invoke_atf() that takes a spl_image_info
argument and then derives the necessary parameters for the ATF entry.
Based on the additional information recorded (into /fit-images) from
the FIT loadables, we can now easily locate the next boot stage.

We now pass a pointer to a FDT as the platform-specific parameter
pointer to ATF (so we don't run into the future headache of every
board/platform defining their own proprietary tag-structure), as
FDT access is already available in ATF.

With the necessary infrastructure in place, we can now update the
support for the ARM Trusted Firmware to dispatch into the
spl_invoke_atf function only if a IH_OS_ARM_TRUSTED_FIRMWARE image is
loaded.

spl: add support to booting with ATF

ATF(ARM Trusted Firmware) is used by ARM arch64 SoCs, find more infomation

SPL is considered as BL2 in ATF terminology, it needs to load other parts
of ATF binary like BL31, BL32, SCP-BL30, and BL33(U-Boot). And needs to
prepare the parameter for BL31 which including entry and image information
for all other images. Then the SPL handle PC to BL31 with the parameter,
the BL31 will do the rest of work and at last get into U-Boot(BL33).

This patch needs work with patches from Andre for SPL support multi
binary in FIT.

The entry point of bl31 and bl33 are still using hard code because we
still can not get them from the FIT image information.
