The current implementation of bcm2835_thermal_ops sets
impl.max_access_size and valid.min_access_size to 4, but leaves
impl.min_access_size and valid.max_access_size unset, defaulting to 1.
This causes issues when the memory system is presented with an access
of size 2 at an offset of 3, leading to an attempt to synthesize it as
a pair of byte accesses at offsets 3 and 4, which trips an assert.
Additionally, the lack of valid.max_access_size setting causes another
issue: the memory system tries to synthesize a read using a 4-byte
access at offset 3 even though the device doesn't allow unaligned
accesses.
This patch addresses these issues by explicitly setting both
impl.min_access_size and valid.max_access_size to 4, ensuring proper
handling of access sizes.
