The perennial problem with u16 << 16 strikes again - the u16 is
implicitly promoted to an int before the shift, which will then become
negative if the highest bit of the u16 was set. Normally this isn't much
of a problem, but in this case tegra_dsi_writel() expects a 64 bit integer
for that argument, and so it will be sign-extended to a very large
unsigned integer if it is negative. Cast bytes to a u32 beforehand to
prevent the implicit promotion and thus this problem.

This patch provides an increased timeout (60ms -> 1s) for SPI
HW-sequencing flash erase operations. Without that the erase for MRC
cache writing on siemens/mc_bdx1 sometimes goes wrong because the
timeout stops waiting for flash cycle completion. It was found
during continuous integration. Investigation showed that the used flash
type takes sporadic (e.g. 5% of the test cycles) more time for completion
of erasing operation if the ambient temperature increases. The measured
time values are in range of data sheet of SPI flash. 60ms is a typical
value. So increasing the value is necessary.
tested on siemens/bdx1; measured time values with increased ambient
temperature of flash were always smaller than worst case value of 1s.
