kernel: bump to 5.4.302

Browse Source 
- update the 5.4 kernel baseline from 5.4.284 to 5.4.302
- rebase the affected generic patches, including the MikroTik build bits and codel backport, to the 5.4.302 source context
- rebase the affected MediaTek TRNG and PWM patches to the new source context
- adjust 993-usb-serial-option-add-u9300.patch so the LONGSUNG U9300 modem patch still applies after the qmi_wwan changes
