fenugrec 8c74128ff6 usb: st_usbfs_v2: allow unaligned buffers for st_usbfs_copy_from_pm() ...

The previous implementation of copy_from_pm assumed the destination buffer
was aligned on a 16-bit boundary. On M0/M0+ cores (stm32F0*, stm32L0*)
this causes a hard fault.
This implementation is from Kuldeep Dhaka's tree; it does a 16-bit copy
only if the destination buffer is aligned, otherwise a bytewise copy.

Fixes GH issues #401, #461
