ARM: pxa2xx: Fix GPIO descriptor tables
Laurence reports:
"Kernel >5.18 on Zaurus has a bug where the power management code can't
talk to devices, emitting the following errors:
sharpsl-pm sharpsl-pm: Error: AC check failed: voltage -22.
sharpsl-pm sharpsl-pm: Charging Error!
sharpsl-pm sharpsl-pm: Warning: Cannot read main battery!
Looking at the recent changes, I found that commit 31455bbda208 ("spi:
pxa2xx_spi: Convert to use GPIO descriptors") replaced the deprecated
SPI chip select platform device code with a gpiod lookup table. However,
this didn't seem to work until I changed the `dev_id` member from the
device name to the bus id. I'm not entirely sure why this is necessary,
but I suspect it is related to the fact that in sysfs SPI devices are
attached under /sys/devices/.../dev_name/spi_master/spiB/spiB.C, rather
than directly to the device."
After reviewing the change I conclude that the same fix is needed
for all affected boards.
