Add NAND secure boot target for ls1043ardb.

- Change the u-boot size defined by a macro for copying the main
  U-Boot by SPL to also include the u-boot Secure Boot header size as
  header is appended to u-boot image. So header will also be copied
  from SD to DDR.
- MACRO for CONFIG_BOOTSCRIPT_COPY_RAM is enabled to copy Bootscript
  from NAND to DDR. Offsets for Bootscript on NAND and DDR have been
  also defined.

We should invalidate the dcache before starting the DMA. In case there are
any dirty lines from the DMA buffer in the cache, subsequent cache-line
replacements may corrupt the buffer in memory while the DMA is still going on.
Cache-line replacement can happen if the CPU tries to bring some other memory
locations into the cache while the DMA is going on.

Merely using dma_alloc_coherent does not ensure that there is no stale
data left in the caches for the allocated DMA buffer (i.e. that the
affected cacheline may still be dirty).

The original code was doing the following (on AArch64, which
translates a 'flush' into a 'clean + invalidate'):
  # during initialisation:
      1. allocate buffers via memalign
      	 => buffers may still be modified (cached, dirty)
  # during interrupt processing
      2. clean + invalidate buffers
      	 => may commit stale data from a modified cacheline
      3. read from buffers

This could lead to garbage info being written to buffers before
reading them during even-processing.

To make the event processing more robust, we use the following sequence
for the cache-maintenance:
  # during initialisation:
      1. allocate buffers via memalign
      2. clean + invalidate buffers
      	 (we only need the 'invalidate' part, but dwc3_flush_cache()
	  always performs a 'clean + invalidate')
  # during interrupt processing
      3. read the buffers
      	 (we know these lines are not cached, due to the previous
	  invalidation and no other code touching them in-between)
      4. clean + invalidate buffers
      	 => writes back any modification we may have made during event
	    processing and ensures that the lines are not in the cache
	    the next time we enter interrupt processing

Note that with the original sequence, we observe reproducible
(depending on the cache state: i.e. running dhcp/usb start before will
upset caches to get us around this) issues in the event processing (a
fatal synchronous abort in dwc3_gadget_uboot_handle_interrupt on the
first time interrupt handling is invoked) when running USB mass
storage emulation on our RK3399-Q7 with data-caches on.

The dwc3_flush_cache() call was declared and used inconsistently:
 * The declaration assumed 'int' for addresses (a potential issue
   when running in a LP64 memory model).
 * The invocation cast the address to 'long'.

This change ensures that both the declaration and usage of this
function consistently uses 'uintptr_t' for correct behaviour even
when the allocated buffers (to be flushed) reside outside of the
lower 32bits of memory.

After enabling log printing to lcd, when the screen starts

    "Synchronous Abort" handler, esr 0x96000045

Checking the source code, we found that the variable "pixels"
gets a wrong value:

    int pixels = VIDEO_FONT_HEIGHT * vid_priv->line_length;

"pixels" here means the value of pixels for a character, rather
than the bytes for a character. So the variable "pixels" is 4
times bigger than it's exact value, which will cause the memory
overflow when the cpu runs the following code:

    for (i = 0; i < pixels; i++)
