I spotted this issue when I wanted to use the largest possible text
mode in UEFI shell at high graphics resolutions. Is it not enough
reason for this commit?

Can you please elaborate this? I've tried to disable UART in "Boot
Maintenance Manager -> Console Options" like this:
```
Console Input Device Select:
PciRoot(0x0)/Pci(0x1,0x0)/Acpi(PNP0303,0x0) [X]
PciRoot(0x0)/Pci(0x1,0x0)/Serial(0x0)/Uart(115200,8,N,1) [ ]
Console Output Device Select:
PciRoot(0x0)/Pci(0x2,0x0)/AcpiAdr(0x80010100) [X]
PciRoot(0x0)/Pci(0x1,0x0)/Serial(0x0)/Uart(115200,8,N,1) [ ]
Console Standard Error Device Select:
PciRoot(0x0)/Pci(0x2,0x0)/AcpiAdr(0x80010100) [X]
PciRoot(0x0)/Pci(0x1,0x0)/Serial(0x0)/Uart(115200,8,N,1) [ ]
```
But after reset, the console is 80x25 and all UART options are checked again.
Also there is a menu "Boot Maintenance Manager -> Console Options ->
Console Output Mode Select" that has "Set Console Output Mode", and it
is always "80x25" without any options for me.
Best regards,
Konstantin Aladyshev
