[PATCH 0/1][SRU][Bionic] add 16-bit width registers support for EEPROM at24 device

[AceLan Kao]

BugLink: https://bugs.launchpad.net/bugs/1876699

[Impact]
Larger EEPROM devices that use 16-bit addresses couldn't be accessed.

[Fix]
The commit is from
https://patchwork.ozlabs.org/patch/545292/

Unfortunately, this commit doesn't get into mainline in the end, so I
migrate the commit to latest kernel and finally get it merged.
https://lkml.org/lkml/2020/4/24/635

[Test]
Verified on Eurotech's platforms.

[Regression Potential]
Low, this patch only changes the behavior of the device which has
AT24_FLAG_ADDR16 flag and change the page_size to 64 if the device name is 24c256.
