package/bcm2835: bump version to 1.62

Changelog (since 1.60):
  - 1.61 2020-01-11 Fixed errors in the documentation for bcm2835_spi_write.
    Fixes issue seen on Raspberry Pi 4 boards where 64-bit off_t is used by
    default via -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64. The offset was
    being incorrectly converted, this way is clearer and fixes the problem.
    Contributed by Jonathan Perkin.
  - 1.62 2020-01-12 Fixed a problem that could cause compile failures with
    size_t and off_t
