Multiple BIOS issues/bugs

   I have:
- Fatal1ty B450 Gaming-ITXac + 1300x (1.20)
- AB350M Pro4 + 2200G (5.00)
- Fatal1ty X370 Gaming X + 9700 (Bristol ridge) (4.90)
- X370 Taichi + 2700X (4.80)
FreeBSD 11.2

For all these MoBos with last BIOS:

1. Asrock settings does not work as intended:
- can set only freq, voltage settings does not work. Mine tests with manual  P-States tunigs show that AMD requires at least 3 filled P-States, freq and voltage must be different. Asrock set only two, indentical records.
- ACPI report to OS wrong data if freq set to non auto - freq and voltage set:
dev.hwpstate.0.freq_settings: 3700/-1 3700/-1 2466/-1
dev.cpu.0.freq_levels: 3700/-1 3700/-1 2466/-1
- I cant disable boost, Asrock settings mode overwrites this.

2. Then AMD PCB settings mode activated
- real voltage in BIOS H/W mon show is less then in minimal P-State
- CPU works like minimal P-State is active
- no performance / CPU temp on manual switch P-State from OS
(sysctl dev.cpu.0.freq=1 / sysctl dev.cpu.0.freq=10000 - show that switch ok, no performance affect)

3. Bristol Ridge CPU REQUIRED PSP=enabled, if psp is disabled - MoBo does not init. Option should be enabled and hidden if bristol ridge CPU installed.

Taichi only

BIOSes after 4.60:
- after load SMBus driver (amdsmb) PCI-e stop work and only reset button helps.
On 4.60 and all prev BIOSes (even 1.xx) - no problem.
On other MoBos with latest BOISes - no problem.
- wrong CPU temperature read (4.80+): CurTmpTjSel show actual temp and CurTmp show something strange 90-110C

Before 4.60
- ACPI report to OS wrong data:
dev.hwpstate.0.freq_settings: 3700/-1 3700/-1 2466/-1
dev.cpu.0.freq_levels: 3700/-1 3700/-1 2466/-1
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225782

Correct looks like this (Asrock settings, all auto):
dev.hwpstate.0.freq_settings: 3500/4331 3000/3450 1550/1331
dev.cpu.0.freq_levels: 3500/4331 3000/3450 1550/1331
or (asus am1)
dev.hwpstate.0.freq_settings: 2050/5070 1850/4635 1650/3712 1400/2968 1200/2291 1000/1902 800/1545
dev.cpu.0.freq_levels: 2050/5070 1850/4635 1650/3712 1400/2968 1200/2291 1000/1902 800/1545

I can provide bootabe FreeBSD images and instructions to fast and easy reproduce these issues.
