mts_mdot_f411re: Fix for Multi-Tech mDot IAR linker script

[hosse005]

Description

Fix for applications targeting the mts_mdot_f411re target with the IAR compiler. Need the reset vector table to also have a 64 kB offset to compensate for the presence of a 64 kB bootloader.

Verified by building and running the mbed-os-example-blinky app successfully with the following environment:

• IAR EWARM 7.80.1
• mbed-cli 1.3.0

Fixes #6181
