cyw43439: gpio_put only sets pins and can't clear them

[kapypara]

The gpio_put function in drivers/wireless/cyw43439/wifi.zig currently only uses OR when updating the output register. which mean values can't be cleared from the output

microzig/drivers/wireless/cyw43439/wifi.zig

Line 817 in 6750f70

reg = reg | @as(u32, value) << pin;

Instead, it should mask the original register value first:

reg = (reg & ~(@as(u32, 1) << pin)) | (@as(u32, value) << pin);
