mtd: Remove mtd_erase_callback() entirely

mtd: mtdpart: Make mtdpart's _erase method sane
The _erase() method of the mtdpart driver, part_erase(), currently
implements offset shifting (for given mtdpart partition) in a weird way:
1. part_erase() adds partition offset to block address
2. parent driver's _erase() method is called
3. parent driver's _erase() method calls mtd_erase_callback()
4. mtd_erase_callback() subtracts partition offset from block address
so that the callback function is given correct address
The problem here is that if the parent's driver does not call
mtd_erase_callback() in some scenario (this was recently a case for
spi_nor_erase(), which did not call mtd_erase_callback() at all), the
offset is not shifted back.
Moreover the code would be more readable if part_erase() not only added
partition offset before calling parent's _erase(), but also subtracted
it back afterwards. Currently the mtd_erase_callback() is expected to do
this subtracting since it does have to do it anyway.
Add the more steps to this procedure:
5. mtd_erase_callback() adds partition offset to block address so that
it returns the the erase_info structure members as it received them
6. part_erase() subtracts partition offset from block address
This makes the code more logical and also prevents errors in case
parent's driver does not call mtd_erase_callback() for some reason.
(BTW, the purpose of mtd_erase_callback() in Linux is to inform the
caller that it is done, since in Linux erasing is done asynchronously.
We are abusing the purpose of mtd_erase_callback() in U-Boot for
completely different purpose. The callback function itself has empty
implementation in all cases in U-Boot.)

Fix up the header's include guard to contain the definition of
dm_priv_to_rw(), which was erroneously added outside of it, by moving
its #endif to the end of the file (i.e. where it belongs). This removes
the risk of compilation errors resulting from the redefinition of that
function where the header might have been (indirectly) included more
than once.

On the iMX7ULP uCOM board, OP-TEE uses the memory region defined by the
maximum DRAM address minus CONFIG_OPTEE_TZDRAM_SIZE, so subtract
CONFIG_OPTEE_TZDRAM_SIZE from the available DRAM size to avoid
conflicts.
Note the OPTEE boot process itself subtracts the DRAM region it
lives in from the memory map passed to Linux.

There are two Linux ioctls which implements tcsendbreak() functionality:
TCSBRK and TCSBRKP
TCSBRK with non-zero parameter implements tcdrain() and with zero parameter
implements tcsendbreak() for duration of 0.25s.
TCSBRKP with zero parameter is same as TCSBRK and with non-zero parameter
implements tcsendbreak() for duration in deciseconds specified by
parameter. TCSBRKP does not have to be provided by older toolchain
versions.
So tcsendbreak() has to either use TCSBRK with zero parameter or TCSBRKP
with any parameter.
Fix code to use TCSBRKP and fallback to TCSBRK with 0.

While here, fix an invalid cast in setup_efi_info(). Note that this
