mb/google/bluey: Increase FW_MAIN_A/B slot size to 8.5MB

Browse source 
This patch increases the size of the FW_MAIN_A and FW_MAIN_B slots to
8.5MB to accommodate APDP, Ramdump and ADSP-lite images. A 5MB
estimated size of QTEE image is also taken into account to avoid future
resizing.

Size required for QTEE:
  Current size -> 2776K, Estimated size -> 5120K (5MB)
  Additional size needed -> 5120K-2776K = 2344K

Size required for new images:
  Ramdump	- 449K
  APDP		- 0.7K
  ramdump_meta	- 0.1K
  apdp_meta	- 1.4K
  ADSP_Lite	- 1192K
  Total		= 1643K

Additional size needed (QTEE + new images):
  2344K+1643K = 3987K

Current Layout of FW_MAIN_A/B slots:
  Total size	- 4608K (4.5MB)
  Used size	- 4126K
  Free size	- 482K

Additional size needed (excluding free size):
  3987K-482K = 3505K

Total size of FW_MAIN_A/B slots:
  4608K+3505K = 8133K

An additional buffer of 591K is included in the final size to
provide room for increase in size of other blobs. So,

Final size of FW_MAIN_A/B slots:
  8133K+591K = 8704K (8.5MB).

TEST=Create an image.serial.bin and ensure it boots on X1P42100.
