The original purpose of mtd_erase_callback() in Linux at the time it was
imported to U-Boot, was to inform the caller that erasing is done (since
it was an asynchronous operation).
All supplied callback methods in U-Boot do nothing, but the
mtd_erase_callback() function was (until previous patch) grossly abused
in U-Boot's mtdpart implementation for completely different purpose.
Since we got rid of the abusement, remove the mtd_erase_callback()
function and the .callback member from struct erase_info entirely, in
order to avoid such problems in the future.

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.)

The spi_nor_erase() function does not call mtd_erase_callback() as it
should.
The mtdpart code currently implements the subtraction of partition
offset in mtd_erase_callback().
This results in partition offset being added prior calling
spi_nor_erase(), but not subtracted back on return. The result is that
the `mtd erase` command does not erase the whole partition, only some of
it's blocks:
=> mtd erase "Rescue system"
Erasing 0x00000000 ... 0x006fffff (1792 eraseblock(s))

Check for zero length in the legacy spi_flash_read() /
spi_flash_write() / spi_flash_erase() functions.
On zero length, return 0 immediately, don't call the underlying method.
Rationale:
- these legacy functions call the _read(), _write() and _erase() methods
of struct mtd
- the DM callers of these methods already check for zero length
- making all callers of these methods check for zero length makes it
possible to remove the check from implementations of these _read(),
_write() and _erase() methods

In the past the env_match() function was used to match envs with

- variable assignment, i.e. string "name=other_value"
The latter is not the case anymore, since the env_match() function is
now used only in env_get_f(), and so we can simplify the function into
a simple strncmp() with an additional comparison to '='.
Let's do this, and since the resulting function is quite simple, let's
also inline its code into env_get_f().

Currently the env_get_f() function's return value behaves weirdly: it

there was enough space in `buf`.
Change the function to always return the actual length of the value of

success. This makes it behave like sprintf().
