Andrzej Głąbek 41c33d7f32 drivers: flash: nrf_qspi_nor: Fix writing from unaligned RAM buffers 
Flash API states that drivers should support write requests without
any restrictions on location or alignment of the source buffer.
Due to hardware limitations of the QSPI peripheral, the nrf_qspi_nor
driver currently fails to perform a write from a RAM buffer that is
not word-aligned. Fix this by using in such case the same mechanism
that is used when the source buffer is located in the internal flash
(copy data to a buffer located on stack).
Also correct the length parameter for writes from this stack-based
buffer to be the actual data chunk length, not always the size of
the buffer (as for CONFIG_NORDIC_QSPI_NOR_STACK_WRITE_BUFFER_SIZE > 4
this may lead to overwriting of some data located next in the flash).
