SPI Slave pin config

[Yoshiyuki Kasai]

I use spi_slave with SDK 9.0.0. SPI slave is working, but there is some current leak when it become system off mode. I think the reason is that MISO is HI-Z at that time. Is it possible to change the configuration like the following?

NRF_GPIO->PIN_CNF[p_spi_slave_config->pin_miso] = 
    (GPIO_PIN_CNF_SENSE_Disabled << GPIO_PIN_CNF_SENSE_Pos) |
    (m_drive_config << GPIO_PIN_CNF_DRIVE_Pos)              |
    (*GPIO_PIN_CNF_PULL_Pulldown* << GPIO_PIN_CNF_PULL_Pos)   |
    (GPIO_PIN_CNF_INPUT_Connect << GPIO_PIN_CNF_INPUT_Pos)  |
    (GPIO_PIN_CNF_DIR_Input << GPIO_PIN_CNF_DIR_Pos);

Thanks. It is useful for me. It said that the SPI slave peripheral is low power by default when the CSN line is high. It is true, but I think MISO should keep low or high. Because MISO is output pin of SPI Slave. What do you think about that?
