ath10k: pci: make host_ce_config_wlan[] more readable

It's much more readable if struct entries in host_ce_config_wlan
are explicitly set.

Void pointers are bad, mmkay.

No functional changes.

ath10k: convert ath10k_pci_reg_read/write32() to take struct ath10k

This is consistent with all other functions.

The error handling was just weird, simplify it.

ath10k: convert ath10k_pci_wake() to return

We should not try to access hw if wakeup fails so add
proper error checking for that. Also add the timeout lenght
to the warning message.

ath10k: simplify ath10k_ce_init() wake up handling

ath10k_ce_init() and the functions it calls wakeup
the chip multiple times. Simplify that to call
ath10k_pci_wake() only once. This also makes it
easier to add error handling when wakeup fails.

ath10k: check chip id from the soc register during probe

ath10k doesn't support qca988x hw1.0 boards anymore. Unfortunately
the PCI id is the same in hw1.0 and hw2.0 so ath10k tries to use
hw1.0 boards anyway. But without hw1.0 workarounds in place
ath10k just crashes horribly.

To avoid using hw1.0 boards at all add a chip id detection
and fail the probe if hw1.0 is detected:

[ 5265.786408] ath10k: ERROR: qca988x hw1.0 is not supported
[ 5265.786497] ath10k: Unsupported chip id 0x043200ff
[ 5265.786574] ath10k: could not register driver core (-95)
[ 5265.793191] ath10k_pci: probe of 0000:02:00.0 failed with error -95

Also add a warning if there's an unknown chip id but continue
the boot process normally anyway.

ath10k: add chip_id file to debugfs

So that's it's possible to query chip id from ath10k anytime.
