rpi4: boot: Update the firmwares for kernel v5.10.95

Update RPi4 firmware files to the latest version available in firmware
stable branch. With the previous firmware, the display subsystem failed
to be initialized properly by the updated VC4 DRM drivers available in
v5.10.95 vendor tree:

root:~> dmesg | grep drm
[    0.655835] vc4-drm gpu: [drm] Couldn't stop firmware display driver: -22
[    0.656074] vc4-drm gpu: bound fe400000.hvs (ops vc4_hvs_ops)
[    1.701692] vc4-drm gpu: [drm] Couldn't stop firmware display driver: -22
[    1.703160] vc4-drm gpu: bound fe400000.hvs (ops vc4_hvs_ops)
[    1.704826] vc4-drm gpu: failed to bind fef00700.hdmi (ops vc4_hdmi_ops): -22
[    1.713616] vc4-drm gpu: master bind failed: -22
[    1.713645] vc4-drm: probe of gpu failed with error -22

The updated firmware files fix the above issue.

The updated files comes from https://github.com/raspberrypi/firmware.git
stable branch, commit 48cd70fe84 ("kernel: Update to latest kernel
5.15.61+ from master branch").
