xDot (STM32L151) mbed_application.c `isr_count` wrongly evaluates to 1

Bug

Target
xDot

Toolchain:
GCC_ARM and ARMCC

mbed-os sha:
mbed OS 5.5.5

Expected behavior

mbed-os-example-bootloader-blinky does not work on xDot. This is because the bootloader does not clear interrupts correctly before handing over control to target application. mbed_application.c evaluates isr_count to 1 on this platform, which is not correct. Manually patching the isr_count to 192 makes the target app start up correctly.
