Add GD25LQ24C 64Mbit chip to spi-nor id table. This chip is used on
rk3399-gru-kevin:

    => sf probe
    SF: Detected gd25lq64c with page size 256 Bytes, erase size 4 KiB, total 8 MiB
    => sf erase 0x600000 0x200000
    SF: 2097152 bytes @ 0x600000 Erased: OK
    => sf test 0x700000 0x1000
    SPI flash test:
    0 erase: 52 ticks, 76 KiB/s 0.608 Mbps
    1 check: 5 ticks, 800 KiB/s 6.400 Mbps
    2 write: 14 ticks, 285 KiB/s 2.280 Mbps
    3 read: 3 ticks, 1333 KiB/s 10.664 Mbps
    Test passed
    0 erase: 52 ticks, 76 KiB/s 0.608 Mbps
    1 check: 5 ticks, 800 KiB/s 6.400 Mbps
    2 write: 14 ticks, 285 KiB/s 2.280 Mbps
    3 read: 3 ticks, 1333 KiB/s 10.664 Mbps

The values are the same as in Linux, except adjusted for the U-Boot
definition of INFO().

This is from Linux's drivers/mtd/spi-nor/gigadevice.c which is GPL-2.0,
but the U-Boot file is marked as GPL-2.0+ (which is AFAICT incorrect,
see the previous patch).
