Add support for Winbond W25X05CL
This commit adds support for the Winbond W25X05CL SPI flash chip. The
Winbond W25X05CL is a 512Kib (64 KiB) SPI flash chip with 4KiB sectors.
I have tested this patch with a Bus Pirate (v3b) and an in-circuit W25X05CL
flash chip using a test clip. Reading, erasing, and writing all function
as expected.
