In the Flash Component description register (FLCOMP) bit 30 reports the
capability of using dual output for fast read operation on the flash
component. According to various SPI Programming Guides (checked for
Panther Point, Lewisburg C620, Apollo Lake and Elkhart Lake) the dual
output is enabled when this bit is set and disabled if not. Currently the
logic displays it the other way around when parsing the descriptor.
This patch changes this so now if bit 30 in FLCOMP is not set, dual read
support for fast read operation is shown as disabled.

* Only 4KiB erase blocks are supported by the primary erase command
* A second erase command for 64KiB pages was added
* More commands were added for status register access etc.
