[Buildroot] [PATCH next 4/5] configs/solidrun_macchiatobin_mainline: bump kernel and U-Boot

[Sergey Matyukevich <geomatsi@gmail.com>]

> Bump U-Boot to version 2018.11. This version supports autodetection of
> SD/eMMC boot source, so we can now enable environment load from SD card.
> Add a U-Boot kconfig fragment that sets SD/eMMC as environment load/save
> device. This avoids stale environment values from the SPI flash. That in
> turn, allows to use the more convenient distro boot which is enabled in
> the default environment.
> 
> Bump kernel to version 4.19.2. This version enables
> CONFIG_PHY_MVEBU_CP110_COMPHY in the arm64 defconfig, so remove it from
> the kernel kconfig fragment. Enable support for SFP modules detection
> and configuration. Leave the PHY drivers for now to keep them built into
> the kernel. The kernel defconfig builds these drivers as modules. But
> that does not work as expected in the default configuration.

Thanks! Verified the changes on MacchiatoBin v2 board:

Tested-by: Sergey Matyukevich <geomatsi@gmail.com>

By the way, it looks like mainline U-Boot v2018.11 still detects only 2GiB
of DRAM on my boards. Meanwhile vendor U-Boot provided by alternative
config solidrun_macchiatobin_marvell_defconfig detects 4GiB.
