AST2600 supports boot from SPI(mmap), eMMC, and UART.
This patch adds the boot mode detection and return the
corresponding boot device type.

The commit b583348ca8 ("image: fit: Align hash output buffers") places
the hash output buffer at the .bss section. However, AST2600 by default
executes SPL in the NOR flash XIP way. This results in the hash output
cannot be written to the buffer as it is located at the R/X only region.
We need to move the .bss section out of the SPL body to the DRAM space,
where hash output can be written to. This patch includes:
- Define the .bss section base and size
- A new SPL linker script is added with a separate .bss region specified
- Enable CONFIG_SPL_SEPARATE_BSS kconfig option

Return CONFIG_SYS_LOAD_ADDR pointing to DRAM space for
spl_get_load_buffer() to allow generic SPL image loading
code (e.g. FIT and Ymodem) to store data in DRAM.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

Add low level platform initialization for the AST2600 SoC.
The 2-stage booting with U-Boot SPL are leveraged to support
different booting mode.
However, currently the patch supports only the booting from
memory-mapped SPI flash.
