[PATCH 02/14] ARM: ARMv7M: Enlarge vector table to 256 entries

[Maxime Coquelin <mcoquelin.stm32@xxxxxxxxx>]

>From Cortex-M4 and M7 reference manuals, the nvic supports up to 240
interrupts. So the number of entries in vectors table is 256.

This patch adds the missing entries, and change the alignement, so that
vector_table remains naturally aligned.
