[PATCH] power: supply: bq27xxx: drop dead data memory update code

[Henrik Grimler]

bq27500, bq27545 and bq27441 had some work done to enable data memory
updates in commit 05045379b274 ("power: supply: bq27xxx: Enable data
memory update for certain chips"), but it seems like it was never
tested on the hardware, and the code has been in #if 0 .. #endif's
ever since.

It has been around 9 years since this dead code was added. Let's drop
it to give a cleaner driver, as no one has apparently needed the code.
