Fix Cortex-M interrupt vector initialization

Using an STM32F103 I ran into a HardFault exception when using DMA2_CH5 with
interrupts enabled.

It seems no interrupt handler is registered by the startup code for this
particular interrupt source. The DMA2_CH5 interrupt is the last entry in the
interrupt list according to STM32F103 reference manual.

Please see attached patch to the startup code on Cortex-M architecture to use
the correct constant (CYGNUM_HAL_VSR_COUNT) when iterating over all interrupts
and installing hal_default_interrupt_vsr().

This patch works for me and allows DMA2_CH5 to signal transfer complete by
interrupt.
