flashchips: Split GD25Q127C/GD25Q128C and add GD25Q128E

Q127C and Q128C are not the same. Q127C doesn't support QPI but Q128C
does. So we need to split the existing GD25Q127C/GD25Q128C into two
separated entries. We also introduce the new flashchip Q128E and merge
it into Q127C.

Datasheet for Q128E: https://www.gigadevice.com.cn/Public/Uploads/uploadfile/files/20220714/DS-00...

Q128E and Q127C/Q128C have compatible main functions, their differences
are:
* Q128E uses 55 nm process, while Q127C/Q128C use 65nm
* Q128E/Q127C does not support QPI
* Q128E have OTP: 3072B, while Q127C/Q128C are 1536B
* Q128E's fast read clock frequency is 133MHz, while Q127C/Q128C are
  104MHZ

So we decided to merge Q128E into Q127C.

We also tested that Q128E could pass flashrom_tester while probing it as
127C/128C, so the main functionalities are compatible.

Change the chip name from GD25Q127C/GD25Q128C to two entries
GD25Q127C/GD25Q128E and GD25Q128C to make it more accurate.

Chip revision history:
- The 'GD25Q127C/GD25Q128C' definition was added in
  `commit e0c7abf219b81ad049d09a4671ebc9196153d308` as 'GD25Q128C' and
  later renamed to 'GD25Q127C/GD25Q128C'

BUG=b:304863141, b:293545382
BRANCH=none
TEST=flashrom_tester with flashrom binary could pass with Q128E,
     which contains probe, read, write, erase, and write protect
