4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Rafał Miłecki <rafal@milecki.pl>

commit 0976eda7915507fe94e07870c19d717c9994b57a upstream.

During implementation of the new API bcm_qspi_bspi_set_flex_mode() has
been modified breaking calculation of address length. An unnecessary
multiplication was added breaking flash reads.

Fixes: 5f195ee7d830 ("spi: bcm-qspi: Implement the spi_mem interface")
