    crypto: bcm - Rename struct device_private to bcm_device_private
    
    [ Upstream commit f7f2b43eaf6b4cfe54c75100709be31d5c4b52c8 ]
    
    Renaming 'struct device_private' to 'struct bcm_device_private',
    because it clashes with 'struct device_private' from
    'drivers/base/base.h'.
    
    While it's not a functional problem, it's causing two distinct
    type hierarchies in BTF data. It also breaks build with options:
      CONFIG_DEBUG_INFO_BTF=y
      CONFIG_CRYPTO_DEV_BCM_SPU=y
    
    as reported by Qais Yousef [1].
