When ENV_IS_IN_UBI is enable, get_mtdparts is called before relocation.

During first get_mtdparts() call, mtdparts is not available in environment,
it can be retrieved by calling board_mtdparts_default(), but following
env_set() do nothing as we are before relocation. Finally mtdparts is
still not available in environment.

At second get_mtdparts() call, use_defaults is false, but mtdparts is still
not in environment and is NULL.

Remove use_defaults bool, only mtdparts criteria is useful.

Fixes: commit 5ffcd50612f6 ("mtd: Use default mtdparts/mtids when not defined
in the environment")

Migrate the BR/OR settings to Kconfig. These must be known at compile
time, so cannot be configured via DT.

Configuration of this crucial variable should still be somewhat
comfortable. Hence, make its fields configurable in Kconfig, and
assemble the final value from these.

While converting CONFIG_SYS_[DI]CACHE_OFF to Kconfig, there are instances
where these configuration items are conditional on SPL. This commit adds SPL
variants of these configuration items, uses CONFIG_IS_ENABLED(), and updates
the configurations as required.

- Important spi-mem fix

The support for DaVinci DM* SoCs has been dropped. The code that used
to be relevant to dm644x is no longer needed. Remove it.

Some SPI controllers can't write nor->page_size bytes in a single step
because their TX FIFO is too small, but when that happens we should
make sure a WRITE_EN command before each write access and READ_SR command
after each write access is issued.

We should allow nor->write() to return a size that is smaller than the
requested write size to gracefully handle this case.

Also, the spi_nor_write_data() should return the actual number of bytes
that were written during the spi_mem_exec_op() operation.

This patch is a combination of two commits backported from kernel:

  commit 630d6bd8a3b4 ("mtd: spi-nor: Support controllers with limit ...")
  commit 3baa8ec88c2f ("mtd: devices: m25p80: Make sure WRITE_EN is ...")

The purpose of "mtd: nand: raw: allow to disable unneeded ECC layouts"
was to allow disabling the default ECC layouts if a driver is known to
provide its own ECC layout. However, this commit did the opposite and
disabled the default layout when it was _not_ selected.

It breaks all the NAND drivers not providing their own ECC layout this
patch fix this situation.

It was tested with the lpc32xx_nand_slc driver.
