eeprom: fix eeprom write procedure

This fixes commit 1a37889b0ad084a740b4f785031d7ae9955d947b:
----------------------->8--------------------
eeprom: Pull out the RW loop

Unify the code for doing read/write into single function, since the
code for both the read and write is almost identical. This again
trims down the code duplication.
----------------------->8--------------------

where the same one routine is utilized for both EEPROM writing and
reading. The only difference was supposed to be a "read" flag which
in both cases was set with 1 somehow.

That lead to a missing delay in case of writing which lead to write
failure (in my case no data was written).
