NFC: nci: export nci_core_reset and nci_core_init

Some drivers needs to have ability to reinit NCI core, for example after updating firmware in setup() of post_setup() callback. This patch makes nci_core_reset() and nci_core_init() functions public, to make it possible. Signed-off-by: Robert Baldyga <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
