[U-Boot] [U-Boot, 2/2] rockchip: defconfig: puma-rk3399: bypass ADC-based boot_mode check

[Philipp Tomsich]

> The boot (and fallback/emergency boot) concept for the RK3399-Q7
> differs from Rockchip's reference platforms.
> 
> On the RK3399-Q7, some of this functionality is present in the
> bootloader itself (and configurable); some is backed in hardware by
> the Qseven BIOS_DISABLE signal to invoke the final stages of fallbacks
> (i.e. either an external boot bypassing on-module memories or falling
> back to the BROM for USB recovery).
> 
> In summary: the ADC-based boot_mode check does not apply for the
> RK3399-Q7 and we therefore disable it (in this commit) by setting
> CONFIG_BOOT_MODE_REG to 0.
