bcm2835-gpiomem doesn't build on ARCH_BCM2835

[notro]

drivers/char/broadcom/bcm2835-gpiomem.c: In function ‘bcm2835_gpiomem_probe’:
drivers/char/broadcom/bcm2835-gpiomem.c:201:26: error: ‘GPIO_BASE’ undeclared (first use in this function)
   inst->gpio_regs_phys = GPIO_BASE;

Maybe non-DT support just can be dropped?

    if (node) {
        ioresource = platform_get_resource(pdev, IORESOURCE_MEM, 0);
        inst->gpio_regs_phys = ioresource->start;
    } else {
        inst->gpio_regs_phys = GPIO_BASE;
    }

Yes, with hindsight it was a mistake to try to make this driver non-DT compatible. I have a patch to remove the non-DT compatibility, and to properly handle the missing resource.

Fixed for rpi-4.1.y and rpi-4.2.y.
