bcm2835: new package

[Thomas:
 - addition of 'depends on BR2_arm' as suggested by Yann.
 - addition of a comment in the Config.in help text that says that
   this library is a pure abomination.
 - fix the hash, since apparently upstream changes the released
   tarballs after they are published.
 - fix license, it's GPLv2, not GPLv2+.]

+	  C library for Broadcom BCM 2835 as used in Raspberry Pi.
+	  It provides access to GPIO and other IO functions on the
+	  Broadcom BCM 2835 chip, allowing access to the GPIO pins
+	  on the 26 pin IDE plug on the RPi board so you can control
+	  and interface with various external devices.
+
+	  WARNING: the opinion of the Buildroot developers is that
+	  such library is a complete abomination as it entirely works
+	  around the standard Linux interfaces to access GPIOs, I2C,
+	  SPI busses or other IOs. The library directly remaps the
+	  hardware registers in user-space, completely bypassing what
+	  the kernel drivers are doing, and potentially conflicting
+	  with them.
