usb: dwc2: gadget: Accept LPM token when TxFIFO is not empty
Set GLPMCFG_LPM_ACCEPT_CTRL_ISOC bit in GLPMCFG register to accept LPM token during ISOC transfers when TxFIFO is not empty. - Added two definitions. #define GLPMCFG_LPM_ACCEPT_CTRL_CONTROL BIT(21) #define GLPMCFG_LPM_ACCEPT_CTRL_ISOC BIT(22) This patch uses GLPMCFG_LPM_ACCEPT_CTRL_ISOC. GLPMCFG_LPM_ACCEPT_CTRL_CONTROL is defined for further use. - Added setting GLPMCFG_LPM_ACCEPT_CTRL_ISOC bit in GLPMCFG register in dwc2_gadget_init_lpm function.
