With bios/UEFI 1.13 and kernel 5.0.7 things seems to work.
I got touchpad working by installing https://github.com/Syniurge/i2c-amd-mp2 (master works, the wip-v16 doesn't work and screwed up a lot of things when i tried it so don't try that version).

git clone https://github.com/Syniurge/i2c-amd-mp2.git master
mv master i2c-amd-mp2
cd i2c-amd-mp2
LANG=C sudo ./dkms-install.sh

First i booted with pci=noacpi and with that touchpad wasn't working with bios 1.13 that uses advanced touchpad, it did work with earlier bios that had basic option for touchpad.
Removing pci=acpi and instead using:
ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2
did the trick for me.

I sometimes needs to toogle wifi after suspend, i haven't tried hibernate.
My laptop is an A315-41 non G but it think the G only means that it also has a dedicated graphicscard.
I haven't tried it out much yet but at least things seems to work now.
