Do not enable mcuboot.read-granularity on DISCO_L475VG_IOT01A

LDong-Arm · LDong-Arm · commit bf3ca3bd2ce5 · 2021-08-24T16:11:22.000+01:00
The majority of flash devices support reading single bytes without
alignment concerns. The config `mcuboot.read-granularity` enables
additional code to handle read alignment, and it comes with a slight
code size and performance overhead.
