ARM: bcm2835: enable all bcm2835-relevant in defconfig

Rebuild bcm2835_defconfig using "make bcm2835_defconfig;
make savedefconfig", and enable manually the following features:

* all bcm2835-relevant drivers (MBOX, WDT, DMA, PWM, SND)
* enable regular stackprotector because CONFIG_CC_STACKPROTECTOR
  disappear
* enable some new dependencies in order to keep LED heartbeat
  ( CONFIG_NEW_LEDS, CONFIG_LEDS_CLASS, CONFIG_LEDS_TRIGGERS )

The following options were removed, because they are enabled implicit:

CONFIG_RD_BZIP2, CONFIG_RD_LZMA, CONFIG_RD_XZ, CONFIG_RD_LZO,
CONFIG_USB_DWC2_HOST, CONFIG_EXT4_FS, CONFIG_EXT4_FS_POSIX_ACL

These options became obsolete:

CONFIG_RESOURCE_COUNTERS, CONFIG_SCSI_MULTI_LUN
