 wireless/wired charging

Hi Greg,

 A demo of “The usage of quick charge type property” is uploaded in
PATCH v11 1/4 drivers/power/supply/qcom_smbb.c.


The usage of the other three properties is about wireless charging.The
code of our driver can refer to the link below.

POWER_SUPPLY_PROP_QUICK_CHARGE_TYPE：
https://github.com/MiCode/Xiaomi_Kernel_OpenSource/blob/umi-q-oss/drivers/power/supply/qcom/qpnp-smb5.c#L1434

POWER_SUPPLY_PROP_REVERSE_CHG_MODE：
https://github.com/MiCode/Xiaomi_Kernel_OpenSource/blob/umi-q-oss/drivers/power/supply/qcom/qpnp-smb5.c#L2572

POWER_SUPPLY_PROP_TX_ADAPTER：
https://github.com/MiCode/Xiaomi_Kernel_OpenSource/blob/umi-q-oss/drivers/power/supply/qcom/qpnp-smb5.c#L2633

POWER_SUPPLY_PROP_SIGNAL_STRENGTH：
https://github.com/MiCode/Xiaomi_Kernel_OpenSource/blob/umi-q-oss/drivers/power/supply/qcom/qpnp-smb5.c#L2609

Thanks，
Wangting
