package/kernel: add spi-gpio-custom module The package makes it possible to create custom SPI buses via GPIO lines. This module is based on i2c-gpio-custom and allows to configure an SPI bus via GPIO lines and expose it to userspace without rebuilding the kernel. This is maily intended to connect microcontrollers and other simple SPI devices without making an ad-hoc kernel driver.

kernel: use older kernel for explicitly setting dependencies It is generally more desirable to use older kernel versions for dependencies, as this will require less changes when newer kernels are added (they will by default select the newer packages). Since we currently only have two kernels (4.14 and 4.19) in master, this patch applies this logic by converting all LINUX_4_19 symbols to their inverted LINUX_4_14 equivalents.
