According to Data Manual(SPRS915P) of AM572x, TI QSPI controller on
DRA74 EVM(rev 1.1+) can support up to 64MHz in MODE-0, whereas MODE-3 is
limited to 48MHz. Hence, switch to MODE-0 for better throughput.
Also, add IODelay parameters for the same.

The USB boot code is too fat and complicated to be included in SPL
(at least for now). So, it was implemented as a separate project
(what we call USB-loader).
The expected boot sequence is as follows:
Boot ROM -> USB-loader -> SPL -> U-Boot proper
The USB-loader loads the SPL and U-Boot proper from a USB memory
onto the locked L2 cache. Then, SPL needs to copy the U-Boot proper
to DRAM, so this mode looks like a NOR boot from the view of SPL.
However, we want to distinguish between (genuine) NOR boot and USB
boot in some places.

UniPhier SoCs are not equipped with dedicated on-chip SRAM. Instead,
locked outer cache is used as RAM area during the early boot stage
where DRAM is not ready yet. This effectively means MMU must be
always enabled while we are in SPL.
Currently, the SPL image for UniPhier SoCs contains the page table
statically defined at compile time. It has been a burden because the
16KB page table occupies a quarter memory footprint of the 64KB SPL
image.
Finally, there is no more room to implement new features in SPL.
Setting aside the NOR boot mode, this issue can be solved by creating
the page table onto RAM at run time.

No special reason for the current stack address 0x0ff08000.
Change it to 0x00100000 to simplify the init_page_table.
There are two types of SoCs in terms of the load address of SPL.
[1] PH1-sLD3, PH1-LD4, PH1-sLD8
SPL is loaded at 0x00040000-0x0004ffff
[2] PH1-Pro4, PH1-Pro5, ProXstream2, PH1-LD6b
SPL is loaded at 0x00100000-0x0010ffff
The new stack area (0x000f8000-0x00100000) should be safe for all the
cases.

Since commit ad1ecd2063 ("fdt: Build a U-Boot binary without device
tree") and commit 03c25bcd26 ("fdt: Build an SPL binary without
device tree"), we can use shorter file names for the output images.
The default configuration for UniPhier SoCs enables CONFIG_OF_SEPARATE
and CONFIG_SPL_OF_CONTROL. In this case, spl/u-boot-spl.bin is the
same as spl/u-boot-spl-dtb.bin. Likewise, u-boot.img is the same as
as u-boot-dtb.img. So, this change of the flow has no impact.
