Update the GW74xx PMIC configuration:
- increase VDD_SOC DVS1 to 0.85V per datasheet
- increase VDD_SOC DVS0 to 0.95V before first DRAM access
- increase VDD_ARM DVS0 to 0.95V to support kernel overdrive voltage (OD)
- remove unnecessary changes to VDD_DRAM as we don't use 3GHz DRAM
- remove unnecessary change to LDO2 as it is unused

It turns out that it is not necessary to declare the VSELECT signal as
GPIO and let the PMIC driver set it to a fixed high level. This switches
the voltage between 3.3V and 1.8V by setting the PMIC register for LDO5
accordingly.
Instead we can do it like other boards already do and simply mux the
VSELECT signal of the USDHC interface to the pin. This makes sure that
the correct voltage is selected by setting the PMIC's SD_VSEL input
to high or low accordingly.

For some unknown reason GNU assembler version 2.31.1 (arm-linux-gnueabi-as
from Debian Buster) cannot compile following code from located in file
board/nokia/rx51/lowlevel_init.S:
kernoffs:
.word KERNEL_OFFSET - (. - CONFIG_SYS_TEXT_BASE)
when CONFIG_SYS_TEXT_BASE is set to 0x80008000. It throws strange compile
error which is even without line number:
AS board/nokia/rx51/lowlevel_init.o
{standard input}: Assembler messages:
{standard input}: Error: attempt to get value of unresolved symbol `L0'
make[2]: *** [scripts/Makefile.build:293: board/nokia/rx51/lowlevel_init.o] Error 1
I have no idea about this error and my experiments showed that ARM GNU
assembler is happy with negation of that number. So changing code to:
kernoffs:
.word . - CONFIG_SYS_TEXT_BASE - KERNEL_OFFSET
and then replacing mathematical addition by substraction of "kernoffs"
value (so calculation of address does not change) compiles assembler file
without any error now.
There should be not any functional change.
