sdcard_image-rpi.bbclass: increase default boot partition size from 40MiB to 48MiB

* 5.10 kernel got a bit bigger especially for aarch64:
  5.10:   22M     deploy/images/raspberrypi4-64/Image-raspberrypi4-64.bin
  5.10:  7.0M     deploy/images/raspberrypi4/uImage-raspberrypi4.bin
  5.4:    16M     deploy/images/raspberrypi4-64/Image-raspberrypi4-64.bin
  5.4:   6.2M     deploy/images/raspberrypi4/uImage-raspberrypi4.bin

* and the space in fat boot partition was already tight:
  Filesystem      Size  Used Avail Use% Mounted on
  /dev/mmcblk0p1   40M   38M  1.7M  96% /

* increase the size to compensate for it, otherwise
  do_image_rpi_sdimg now fails with:
