Add support for GigaDevice GD25Q32 32 Mbit (4 MB) SPI Flash (see datasheet: http://www.gigadevice.com/UserFiles/GD25Q32_Rev0.2(1).pdf) used in Hame MPR-A1 and clones, and for GigaDevice GD25Q64 64 Mbit (8 MB) SPI Flash used in 
Hame MPR-A2 devices (datasheet: http://www.gigadevice.com/UserFiles/GD25Q64.pdf).
