cr50: uart: increase console tx buffer sizze
Sometimes default buffer size in not enough to collect debug
information generated before console is initialized.
This helps when debugging, allowing to enable fairly large amount of
data printed before console is available, could be reduced if memory
becomes tight.
BRANCH=none
BUG=none
TEST=early debug information previously truncated is printed fully
now.
