ath10k: wake up device before accessing registers

commit 1aaf8efb ("ath10k: disable PCI PS for QCA988X
and QCA99X0") partially reverts pci soc powersave support added by
commit 77258d40 ("ath10k: enable pci soc powersaving"). While
reverting the change, pci wake up function is called after accessing
pci registers instead of prior to access. The assumption is that chip
is woken up before accessing its registers.Though this change does not
fix any known issues, this might help to avoid unknown or low power
platform specific issues.
