Changes to implement in order to remove the external GPS antenna:
- Remove U7606 and C7620
-- Merge C7601 and C7630 into a single capacitor, or remove them completely
+- Merge C7601 and C7630 into a single capacitor.
+
+ Following the reference designs from Atmel and u-blox which put a
+ value between 8.6 pF and 47 pF, with the remark that exact values
+ depend on the layout, we use 22 pF.

- Remove U7605, R7620, C7623, R7613, R7614, C7629, C7628 (external
antenna power sense)
- Remove R7615, Q7602 and R7617. Connect R7610 to LNA_AVDD.
+- Remove R7617 and C7623 (pull-down and buffer for VCONT)
+- Remove CON7602, C7631, and L7609 (external antenna connection)
