Subject: [PATCH] EEPROM emulation: wrong flash sector used for some F7
 variants

Default configuration for F76xx and F77xx chip is single bank.
But HAL define FLASH_SECTOR_TOTAL doesn't represent the real number of sector,
but the maximum number of sector (for single and dual bank).
So for variants using F76xx and F77xx chip,
we must define FLASH_BASE_ADDRESS and FLASH_DATA_SECTOR according to default sector number.

Variant concerned: NUCLEO_F767ZI and REMRAM

Fixes #297
