ANDROID: GKI: db845c: add pcie_capability_clear_and_set_word to the symbol list

In commit 811ec8bc ("wifi: ath11k: Use RMW accessors for changing
LNKCTL"), the ath11k driver adds a call to
pcie_capability_clear_and_set_word which is not in the db845c's exported
symbol list, so the build breaks.  Fix this up by adding the symbol to
the correct list (it's already part of the Android preserved KABI list
in other targets.)
