Fabrice Gasnier e44463f267 serial: stm32: fix clearing interrupt error flags 
[ Upstream commit 1250ed7114 ]

The interrupt clear flag register is a "write 1 to clear" register.
So, only writing ones allows to clear flags:
- Replace buggy stm32_clr_bits() by a simple write to clear error flags
- Replace useless read/modify/write stm32_set_bits() routine by a
  simple write to clear TC (transfer complete) flag.

Fixes: 4f01d833fd ("serial: stm32: fix rx error handling")
