drivers: ieee802154: cc13xx_cc26xx: use HwiP_construct to connect CPE0

Browse source 
IRQ_CONNECT() can only be called at one location to connect the irq for
CPE0. This commit modifies the driver to call into the HwiP layer in TI
HAL so that TI's RF driver can do the same when connecting the irq.

Fixes #25216
