wifi: ath12k: use select for CRYPTO_MICHAEL_MIC

Let ath12k select this option automatically which makes building
more intuitive if the user enables this driver (rather than the
driver not building unless CRYPTO_MICHAEL_MIC is explicitly enabled).

Further investigation shows that ath11k and ath12k are the only who use
'depends on' with CRYPTO_MICHAEL_MIC:

./drivers/net/wireless/intel/ipw2x00/Kconfig:	select CRYPTO_MICHAEL_MIC
./drivers/net/wireless/intersil/hostap/Kconfig:	select CRYPTO_MICHAEL_MIC
./drivers/net/wireless/intersil/orinoco/Kconfig:	select CRYPTO_MICHAEL_MIC
./drivers/net/wireless/ath/ath11k/Kconfig:	depends on CRYPTO_MICHAEL_MIC
./drivers/net/wireless/ath/ath12k/Kconfig:	depends on CRYPTO_MICHAEL_MIC
./drivers/staging/rtl8192e/Kconfig:	select CRYPTO_MICHAEL_MIC
./drivers/staging/ks7010/Kconfig:	select CRYPTO_MICHAEL_MIC
