mb/google/rauru: Increase RW firmware sections size to 1756KB

Browse source 
The RW_A and RW_B firmware sections are increased by 256KB, from 1500K
to 1756K, to support larger firmware images. With bootsplash enabled,
the remaining space in these sections is approximately 15KB, which is
insufficient to hold the bootsplash assets. This increase provides the
necessary space. Additionally, with more features anticipated from the
payload (depthcharge), this extra space serves as a reserve to prevent
future build failures due to insufficient space.

The RW_LEGACY section is also adjusted to fill the remaining space.

WARNING: Please do NOT cherry-pick to rauru firmware branch.
